Artwork/INT As a person with more than 20 years of research on Ho Guom turtles, Assoc. Prof. Dr. Ha Dinh Duc, former senior lecturer at the University of Natural Sciences (Hanoi National University) still has many doubts. Hoan Kiem Lake turtle is the only species loài Assoc. Prof. Dr. Ha Dinh Duc said that ten years ago, the Asian Turtle Conservation Program posed the problem of searching for individual Ho Guom turtles living in other places to pair for the purpose of species conservation. Since 2006, when he discovered that Dong Mo Lake is also likely to have at least one individual of Ho Guom tortoise, he disagreed on the subspecies. Although he went to the place and studied on photos, he found that the Dong Mo lake turtle was completely different in terms of the Sword Lake turtle morphology. Sword Lake turtle is a new species of turtle, the world’s scientific name is Rafetus leloii because this turtle is associated with the legend of King Le returning his sword on Luc Thuy lake in the 15th century, the lake changed its name to Hoan Kiem lake (Ho Guom). . The word “Rafetus” is the name of the genus of turtle, which is derived from the name of the river Raft in India. “leloi” is the species name, named after Le Loi. The person associated with the legend returns the Treasure Sword to the Turtle God. As a rule, the species name is one word, not capitalized, so the two words Le Loi write together as leloi, and add the character ‘i’ to become leloi. In the International Conference “Sustainable Development – Hanoi Capital – City of Culture, Heroes, For Peace” on the occasion of the 1,000th anniversary of Thang Long – Hanoi, once again Assoc. Prof. Dr. Ha Dinh Duc again Announcement on Sword Lake Turtle a new species of tortoise for science. “It can be affirmed that the Asian Turtle Conservation Program has never studied the Sword Lake Turtle in Hoan Kiem Lake but only investigated the Rafetus species. Dong Mo turtle and Chinese tortoise are not Sword Lake turtles”, said Assoc. Prof. Dr. Ha Dinh Duc. Sword Lake Turtle has the largest size of freshwater turtles in Southeast Asia, as well as in the world. Ho Guom tortoise has a white spot on the top of its head and is slightly skewed to the left. Eyes are rounded slightly upward, but do not rise above the surface of the head. The nostrils open to the anterior limit of the anterior jaw bone. The ivory-white horns cover the anterior jaw bone. The fleshy lip encloses the outer margin of the upper jaw and the posterior half of the lower jaw. The back of the head, neck and carapace are light gray. The underside of the chin, neck and bib are pale pink. The carapace is oval in shape, the spine is slightly concave, without spots or stripes. The shell is covered with soft frilled skin that extends beyond the outer margin of the carapace. The fringe of the skin is thin, the back is elongated and slightly cambered. The upper horn covers the anterior jaw bone and the anterior half of the maxillary bone. The lower horn covers the anterior half of the dentate bone and the anterior part of the coronal bone. The limbs are very strong, the feet have wide swimming webbed and have 3 large horn claws. Assoc. Prof. Dr. Ha Dinh Duc said, in history books as well as in legends, there are no documents or stories about a large turtle that once lived in Luc Thuy Lake. It was not until the 15th century that people knew about this turtle through the legend of Hoan Kiem of King Le. So far, there are no documents or information about this large turtle in any water body of Hanoi. Based on the results of comparative research on morphology with large soft-shelled turtles in the world, as well as in Southeast Asia, and discussed with international turtle researchers, such as: Prof. Kraig Adler – University Cornell (USA) and two other experts, Dr. William P. McCord and Dr. Patrick J. Baker, Assoc. Prof. Dr. Ha Dinh Duc found that Hoan Kiem Lake turtle species is completely different. Assoc. Prof. Dr. Ha Dinh Duc. Sword Lake has only one “turtle” “Someone said there are 2-3 “turtles” in Hoan Kiem Lake. But from the time I started researching until the “old man” passed away, I confirmed that Sword Lake had only one “old turtle”. Even when the “grandfather” was weak, everyone trembled when deciding to bring him up. Seeing 2 bubbles of water, many people said that there were 2 “old turtles”, after picking up the “tools”, they thought that there was another “tool”, possibly bigger. However, there is nowhere to catch. Personally, I find that “old turtle” has actions that are really difficult to explain”, Assoc. Prof. Dr. Ha Dinh Duc shared. In many interviews with the press decades ago, Assoc. Prof. Dr. Ha Dinh Duc always expressed the need to find additional sources, because he affirmed that Hoan Kiem Lake has only one “turtle”. . In 2016, the “old turtle” died, he was also a consultant to make a template to look like “the old man” as when he was alive. At present, despite his advanced age, whenever he hears that there are descendants of the “grandfather” he is on the road again. Assoc. Prof. Dr. Ha Dinh Duc’s whole life has been with the University of Hanoi (now the University of Natural Sciences, Vietnam National University, Hanoi). At the age of “rare and old”, Assoc. Prof. Dr. Ha Dinh Duc still has many concerns with Hoan Kiem turtles. On December 18, 2020, the Hanoi Department of Agriculture and Rural Development, in collaboration with the Asian Turtle Conservation Program (ATP), announced the sex determination results of Hoan Kiem turtles in Dong Mo Lake. Hanoi). The results of genetic testing published by scientists have confirmed that the female turtle caught in October 2020 is a species of Rafetus swinhoei, a soft-shell turtle that is on the verge of extinction. This tortoise is also known as Giai Sin-hoe – Hoan Kiem Turtle. Assoc. Prof. Dr. Ha Dinh Duc also visited the place to see this trapped turtle. He said that although the genetic test results match with the Ho Guom tortoise, he is still “troubled”. Because in terms of appearance, the individual turtles in Dong Mo and Xuan Khanh lakes are not like the “old turtle” of Hoan Kiem Lake as he has known so far. To classify turtles, people rely on morphological characteristics and genetic testing. According to his observations, the Dong Mo turtle does not have the same characteristics as the Sword Lake turtle. “I observed that this turtle’s head is more pointed, the snout is more pointed, and has a very different pattern. The structure of the turtle’s eye is also not the same as that of the Ho Guom turtle I know. I have no knowledge of genetics or genetic engineering, but I am skeptical. Sword Lake Turtle is a new, endemic and rare species of turtle, but this turtle in Dong Mo looks like many common turtle species. I think it is possible that it is the same species of turtle, but belongs to a different species, a different breed… Hopefully scientists will clarify this with concrete evidence,” wondered Assoc. Prof. Dr. Ha Dinh Duc. Currently, there are two specimens of Ho Guom turtle. The first specimen died on June 20, 1967 and the second specimen died on January 19, 2016. The second specimen is plasticized according to modern German technology, which can be preserved for a long time.

Estimated cost to build a level 4 house with an area of ​​​​45m2 How to calculate the cost of building a house = Raw area x Wages in m2. To help homeowners better visualize this calculation, the article takes an example of the cost of building a level 4 house with an area of ​​​​45m2. Rough area = Foundation + 1st Floor + Roof The foundation: occupies 50% of the area = 45m2 x 50% = 22.5m2 1st floor: occupies 100% of the area = 45m2 The roof has 3 different roof types, accounting for different percentages: Flat roof: 70% of the area = 70% x 45m2 = 31.5m2 Thai roof: Occupying 50% of the area = 50% x 45m2 = 22.5m2 Corrugated iron roof, tile roof: 30% of the area = 30% x 45m2 = 13.5m2 The total area of ​​a level 4 house with an area of ​​​​45m2, choosing a corrugated iron roof, is: 22.5m2 + 45m2 + 13.5m2 = 81m2 Construction unit prices on the market today are calculated in two ways: The first way: Construction contractor, finishing labor, the cost ranges from 3 million VND to 3.5 million VND/m2 using mid-priced materials. Applying the formula to calculate the cost of building a level 4 house with an area of ​​​​45m2, choosing the corrugated iron roof just calculated above, we have: 81m2 x 3,000,000 = 243,000,000 VND. The second way: The contractor takes care from a to z – Turnkey, the cost ranges from 4.5 million VND to 6 million VND/m2, choosing materials from average to good. Applying the formula to calculate the cost of building a level 4 house with an area of ​​​​45m2, choosing the corrugated iron roof just calculated above, we have: 81m2 x 4,500,000 = 364,500,000 VND. This unit price will fluctuate depending on different locations, depending on the price of raw materials as well as the cost of labor. However, applying the correct formula is possible to calculate the cost of building a flat roof or a corrugated iron roof for your house. The unit price of rough construction does not include the cost of interior equipment such as: house tiles, toilet tiles, tiles, etc. Other costs when building a level 4 house With the cost of paint, there are two types of putty with two different qualities. High-grade paint is priced at 60,000 VND/m2 and medium quality paint is priced at 35,000 VND/m2. Applied to calculate the cost of paint for two level 4 houses, we have the formula: Floor area x unit price of paint per m2 x 4 Where: 4 is the unit factor of 4 walls to be painted. Depending on the region, the locality will have different unit prices, but just by applying the correct formula, you can calculate the cost of painting your level 4 house with different areas. For example: The cost of painting for a level 4 house with an area of ​​45m2, choosing a high-class paint line that costs VND 60,000/m2 is 45m2 x 60,000 VND/m2 x 4 = VND 10,800,000 The cost of painting a level 4 house with an area of ​​45m2, choosing a high-end paint line that costs VND35,000/m2 is 45m2 x 35,000 VND/m2 x 4 = 6,300,000 VND Next to the cost of house tiles, similar to paint, there are also two different types of tiles for homeowners to choose from. High-end floor tiles are priced at 300,000 VND/m2 and average floor tiles are priced at 150,000 VND/m2. The formula for calculating the cost of tiles is: Floor area x unit price in m2. The cost of floor tiles for a level 4 house with an area of ​​​​45m2, choosing high-class tiles for 300,000 VND/m2 is 45m2 x 300,000 VND/m2 = 13,500,000 VND The cost of floor tiles for a level 4 house with an area of ​​45m2, choosing an average tile is quite expensive at 150,000 VND/m2 is 45m2 x 150,000 VND/m2 = 6,750,000 VND For houses that use tiles for the roof, the cost for 1 tile is 30,000 VND/piece, 10 bricks per square meter, labor cost is 5,000,000 VND/m2. The total cost of finishing tiles for a 45m2 house is 20 million VND. All prices are for reference only! Some compact, low-cost models of level 4 houses can be referred to:

Chengdu is an important town in Southwest my country. In recent years, it has developed rapidly, its economy is getting better and better, and its urban construction is also changing with each passing day. In recent years, it has also been doing well in tourism and has become a popular tourist city with a high status in tourism. The top of the list. So after staying in Chengdu, I most want to eat Sichuan Sichuan food, just walk around. 1. I visited Daci Temple in Chengdu first. It feels very similar to Jing’an Temple in Shanghai, but there is no charge here. Daci Temple is located in the downtown area of ​​Chengdu, which can be called the center of Chengdu’s city center. Daci Temple is also an ancient temple with a long history. It is said that Master Xuanzang was ordained in this temple and is also known as “Aurora The first jungle”. This monastery is very large and is located in the city center, so there are many tourists, many letters and incense. In fact, I have been here in 2015, and I am still familiar with it. Especially after a few years, there have been some new buildings and changes in the temple, but the temple is still free. Do not buy tickets. This reminds me of the Jing’an Temple that I visited during my visit to Shanghai in January. The two are very similar. Both are in the downtown area, but the Jing’an Temple costs 50 yuan, which feels a bit too much. So I think Daci Temple is more friendly to the people, there are many tourists, the incense is also prosperous, the temple is beautiful, it is worth seeing. 2. When visiting Daci Temple in Chengdu, I did not expect that there is a very good tea shop: Daci Tea Garden. There is an important common people’s culture in Chengdu, that is, tea culture. Therefore, there are many tea shops in Chengdu, and you will even see many tea stalls on the street. There is also a tea shop in Daci Temple: Daci Tea Garden. The tea garden is located in the Daci Temple. The environment is very good and quiet. There are several kinds of tea, and the quality is good. The price is 30 yuan per person, which is small and expensive. There happened to be a performance that day. I thought it was a Sichuan opera at first, but it said “Sichuan Qingyin” on the stage. I don’t know what it was. Later, the staff told me that there would be performances only on Wednesdays. I was lucky enough to encounter it. Daci Temple is located in the central area of ​​Chengdu. Tickets are not required here. The environment is very good. Friends who recommend to visit Chengdu should come to see it. And drinking a cup of tea, listening to Sichuan music, Sichuan music, holding a bowl of tea, and with the ups and downs of the music, it must be a good choice and taste the life of the Shu people. Anyway, I sat all afternoon and poured some tea… 3. Checking in Taikoo Li, I did not expect that Apple and Nike stores are still very popular. After visiting Daci Temple, I had an afternoon tea, and then went to visit the famous Taikoo Li in Chengdu. This is definitely a high-end consumer place. Visitors need to take their temperature and show their health code when entering the streets. Although there are not many people, there seems to be business in each store. You can also see the consumption pattern in Chengdu. There are a lot of famous brand stores here, and world-class luxury brands are also particularly conspicuous and dazzling. The most eye-catching ones are Apple and Nike stores, which have a lot of customers. I am a little bit emotional when I think of boycotting them not long ago. But I am not interested in this kind of place, mainly because my consumption ability can’t keep up, so I go around and watch the flowers. Even if I have been there, I don’t know if others have my “check in” mentality. Finally, I went to the surrounding “Long Chaoshou” and ate a bowl of won stew, and came back beautifully… 4. Many temples in Chengdu do not charge any fees. Why does Qingyang Palace require 10 yuan tickets? In Chengdu for two days, there is no charge for visiting Daci Temple and Wenshu Monastery, but you still have to buy a 10 yuan ticket to visit Qingyang Palace. Qingyang Palace is a Taoist site. It was built here very early, but it was repeatedly destroyed by wars. The existing buildings were all built during the Kangxi period of the Qing Dynasty. I visited here in the winter six years ago. At that time, the ginkgo trees in the garden were very beautiful. I stayed for a long time and took a lot of photos. At that time, Qingyang Palace collected tickets. I didn’t expect to keep collecting it like this. Is the fee a Taoist venue? This time, because I was already familiar with it, I felt that there was no major change, so I didn’t stay too much. The biggest change here is that there is more room for drinking tea and there are more people, but instead of drinking tea here, I chose to go to Wenshu Monastery for tea. There are two monasteries that do not charge, Daci Temple and Wenshu Monastery. Tea was paid 30 yuan and 18 yuan, while Qingyang Palace only cost 10 yuan to buy tickets. Later, someone said that although Qingyang Palace accepts tickets, the tea inside is cheap. Unfortunately, I didn’t taste it. I don’t know the specific taste and price. Who knows why the Qingyang Palace continues to accept tickets? Some people say that the incense of teaching Buddhism is very strong, so Qingyang Palace is not rich, maintenance and management need money, and the 10 yuan ticket is not much, everyone can accept it, right? 5. Chengdu Wenshu Monastery is a provincial-level cultural preservation unit, but there is no charge here, and visitors can enter at will. As mentioned earlier, Daci Temple does not charge tickets, and there is also an important monastery called Wenshu Monastery, which does not charge any fees. Wenshu Monastery is located in Qingyang District, Chengdu, and was built during the Daye Period of the Sui Dynasty (605-617). It was rebuilt in the thirty-sixth year of Kangxi (1697) and renamed Wenshu Monastery. It is one of the national key Buddhist temples designated by the State Council, the first of the four major Buddhist forests on the upper and lower reaches of the Yangtze River in China, and a key cultural relics protection unit in Sichuan Province. In fact, there is a place for relaxing tea here, the price is lower than that of Daci Temple (maybe there is a reason for the performance). I sat down and asked for high mountain green tea for 18 yuan. It feels so-so, the most ordinary tea. It’s even lower while drinking. In addition to the environment, the service here is also poor. You have to make your own tea, which means you will be given a set of tea sets and a bag of tea after you pay, and then you will find a seat and make tea with water. Chengdu people like gaiwan tea. Soon I discovered that some people use tea sets differently from mine, and there is more than one person. I quickly thought about my own, and finally confirmed that I was right, and the wrong person was someone else, and see if this one is wrong. . However, something embarrassing still appeared. Suddenly something fell from the sky and hit my pants. I was puzzled. I looked up and saw a bird. I understood that it was bird dung. Fortunately, I didn’t fall into the teacup… I can’t sit still, I want to go back and wash my pants…
