The feudal power system established by the Qin dynasty laid the basic foundation for the political structure of later Chinese feudal dynasties. In addition, the policies and systems that divided the country into districts, districts and hukou at that time also had a great impact on the development of the next generations. When posterity looks back on Qin Shi Huang’s journey to unify China from a modern perspective, they must also recognize that this glorious path has timeless inspirational power. The Qin people were originally just horse breeders for the Zhou royal family, then rose to the status of vassals in the Zhou Dynasty (795 BC-771 BC). So why is it that Qin Shi Huang – the king of an ordinary vassal state – was able to unify the six countries and become one of the greatest emperors in Chinese history? Historians say that the secret lies in the weapons of the Qin army: The Qin army possessed powerful weapons, far superior to other vassal countries. Prior to the unification of the six states, the kingdom of Qin was a prosperous vassal state through the reform of the “Transformation of Shangyang” (implemented twice in 356 BC and 350 BC). This reform greatly increased the productivity of Qin society and promoted the development of weapons to a certain extent. Experts said that in the excavation sites of the terracotta army, bronze weapons account for a very large proportion. While the forging and metallurgical technology of the other vassal countries were still quite backward, the state of Qin – a country that valued weapons – had made great progress in this field. Earn copper The bronze swords unearthed next to the terracotta warriors are the clearest evidence of the advancement in forging and metallurgy techniques of the Qin Dynasty. After research, it was found that these bronze weapons were superior to the other six vassal states, the main reason being that the Qin state at that time had mastered the method of making alloys. Their craftsmen also tried to apply the proper proportions of alloys to the military field. Some experts believe that the ratio of copper to tin in the weapons of the Qin army at that time was very reasonable and scientific, especially the tin content was much higher than before, helping bronze weapons. of the Qin army was much harder and sharper. It can be seen that these swords not only have anti-rust treatment, but their length is also about 20 cm longer than swords in other countries. Qin Crossbow The second most notable weapon is the Qin crossbow. The Qin crossbow was developed by the Qin state on the basis of the bow and arrow, but its damage is far beyond the ordinary bow and arrow. Conventional bows and arrows have a limited range, low accuracy, and can only shoot one shot, so soldiers are easy to fall into the attack range of the draft. To improve this problem, the Qin crossbow was born. Through a series of design reforms, the Qin crossbow’s hit rate has been greatly improved. Furthermore, crossbow design parts and components are also standardized and uniform across the country. As a result, when a weapon is damaged, it can be quickly replaced or repaired to immediately return to combat. In addition, the Qin crossbow also has a user-friendly design, minimizing the possibility of soldiers injuring themselves. Three-sided arrow Another notable weapon is the three-pointed arrow that the Qin army used. Thanks to the excellent craftsmanship of the Qin Kingdom craftsmen, this arrow has extremely strong penetrating power. It possesses a unique three-sided design that reduces drag to a minimum after firing. This is also a weapon that other vassal countries do not have. Precisely because of possessing weapons much more sophisticated than those used by the armies of other vassal states, New historians argue that the Qin Dynasty possessed “divine objects” that should not have existed at the time. In addition, the principle of standardizing the manufacture of weapons throughout the territory of Qin also helped soldiers improve their combat capabilities. It can be seen that at that time, the Qin Dynasty was ahead of other vassal countries in both economic and technical aspects. It is not surprising that the Qin Kingdom became the ultimate victorious state and unified China.

After the battery is fully charged, the fan will work for 6-10 hours continuously, even on rainy days without sunshine. In addition, users can use grid electricity to charge the battery for storage and use. Solar fans are causing fever in the market this summer Currently, on the market, these fans come from many places such as: China, Korea, Vietnam, … with very diverse prices, depending on size and function. In which, the lowest price is about 200,000-300,000 VND (mini fan), tree fan costs 800,000-2 million VND. Many fan lines are being discounted by 20-50% to attract buyers.

With “divine” functions, especially without consuming electricity, this type of solar fan immediately caused a fever in the market and was sought after by many people. Mr. Nguyen Hung – an employee of an electronics store in Ho Chi Minh City – said that at this point, the demand for cooling fans has begun to increase sharply, in which the solar fan line is the best-selling model. . As at the beginning of summer, his shop sold about 300 solar fans, at the peak of last year’s heat, he sold up to 800 units. Many fan models are having super cheap prices to attract buyers Similarly, Mr. Hoang Van Binh – an employee of an electrical appliance store in Thanh Xuan (Hanoi) – also said that in recent years, the price of electricity has tended to increase, people have the need to buy and use electricity.

According to him, this type of fan is often suitable for low-rise houses, level 4 houses rather than high-rise buildings and apartments like in the city. Because the fan and solar panels are separate, it is necessary to choose a location to mount the panels to catch the sun (roof, rooftop, balcony, front yard, …) then connect to the fan set. Therefore, with high-rise buildings, moving equipment is quite difficult. But Binh also admitted, when it rains, the charging capacity of the fan will be poor, so in the prolonged rainy season solar fans will not be able to promote their full benefits.

Moreover, the life of the battery is usually only 2-3 years, then it has to be replaced at a considerable cost. In addition, the capacity of the battery will determine the operating time of the fan, the battery is designed with a high capacity, the better the charge will be and vice versa. Limit the selection of multi-function rechargeable fans that are equipped with lights, alarms or clocks… because these features consume power from large batteries, making it easier for the battery to fail faster. Users should not be greedy, but buying low-quality fans will have many potential risks, so consider when choosing and need to choose to buy products of reputable brands and addresses.
