The behavior of Mr. Qian Xuesen is in line with the behavior of Huo Qubing and others that “the Huns are not extinct, why do they make their homes?” It is precisely because of the existence of people like them that our nation can survive the crises again and again. His rocket technology has directly improved our country’s scientific and technological strength for decades, and has reached the point where it can threaten our most powerful enemy. However, what is not known is that Qian Xuesen’s success is inseparable from his beautiful wife, Jiang Ying.

How beautiful was Qian Xuesen’s wife Jiang Ying when she was young? This group of out-of-print old photos amazed time. We now also have many beautiful female stars, most of them are also young, beautiful and white, such as Liu Yifei, Yang Mi and others. But if everyone saw the photos of Qian Xuesen’s wife Jiang Ying, they would think that these stars are incomparable to Jiang Ying. Let me show you Jiang Ying’s photos first.

Jiang Ying was born in a famous family and was the daughter of Jiang Baili, a famous military theorist in modern China. She was born in 1919 and was 8 years younger than Qian Xuesen-which was not a huge gap at the time. At the same time, Jiang Ying is also very talented. She is not a person who can only rely on Qian Xuesen’s reputation to become famous. To some extent, she also sacrificed her music career for Qian Xuesen to a certain extent. Qian Xuesen once said to Jiang Ying himself:

“In these years, I have wronged you. You could have become a famous female singer.” However, Jiang Ying’s answer is more wise and warm: “China can lose me a singer, but you cannot be a rocket expert.” Jiang Ying’s musical talent is unquestionable, even if she gives more in her life. Qian Xuesen was a “supporting role”, but she still made good music scores. She taught at the Central Conservatory of Music for 45 years and trained 26 personal disciples. Among them, Jiang Yong, Fu Haijing, Zhu Ailan, Duoji Tsering, Yang Guang, and Zhao Dengying were all internationally renowned musicians. However, such a musician has taken the initiative to act as a supporting role for Qian Xuesen for most of his life. During his stay in the United States, Qian Xuesen devoted himself to study and research. We all know that the great scientists in history were too sloppy in their clothes because they were too focused on science, such as Newton and Einstein, they looked very sloppy, but Qian Xuesen was not like that. Because he has a good wife, Jiang Ying acted as his nanny during her stay in the United States. As an outstanding musician, she put down the piano and music, and picked up Qian Xuesen’s dirty clothes. This is for a talented woman like Jiang Ying. , It is not easy. Not only that, every time Qian Xuesen goes to some high-end parties, Jiang Ying is also responsible for dressing him up and making him handsome. For this reason, Jiang Ying once said somewhat aggrieved:

“It is not easy to be Mrs. Qian Xuesen. At that time, he was a professor in the upper class in the United States. He had to change and wash his clothes every day. If I ironed his shirt, he would criticize me.” However, even though he was very “blaming”, in the bottom of his heart, Jiang Ying was very satisfied with her husband. The ancients said: A scholar dies for a confidant, and a female is a person who pleases oneself. For a woman, what could be happier to marry a talented husband like Qian Xuesen? Even during the period when Qian Xuesen was under house arrest in the United States, Jiang Ying still encouraged and supported her husband, and was gratified for his patriotism. However, in the face of Jiang Ying’s tenderness, although Qian Xuesen is sometimes “incomprehensible” because he is too focused on technology, but most of the time Qian Xuesen cherishes his wife very much. He knows that he spends all his time on scientific research and rarely accompanies Jiang Ying as a “beauty”, so he often feels ashamed of Jiang Ying. In order to express his guilt, Qian Xuesen cooks for Jiang Ying whenever he has time. What is not known is that Qian Xuesen, as a great scientist and a gourmet master, cooks very delicious food, and Jiang Ying also enjoys this kind of “feedback” from her husband. During those difficult years in the United States, Jiang Ying was always responsible for grocery shopping, and Qian Xuesen was responsible for cooking. It can be said that the two have the hardest career and the strongest love for a while. It is precisely because of this mutual affection that the relationship between the two of them is particularly harmonious. Once Qian Xuesen went to accept the award and said romantically to Jiang Ying: “The award (Jiang Ying) belongs to me, and the money (Qian Xuesen) belongs to you.” Jiang Ying also understood as soon as he heard it, and said: “Say it, award (Jiang) Ying) belongs to you, and the money (Qian Xuesen) belongs to me.” They both regard each other as their entirety, and they also regard themselves as part of each other. This kind of love is always inseparable. It is written in Zhouyi:

“Heaven is inferior to the earth, and the universe is determined. The inferior is high to Chen, the noble and the inferior. The movement is constant, the rigidity and softness are broken. The squares are gathered together, and things are divided into groups. Seeing it. It is the reason why the strength and the softness, the gossip sway, the drum with thunder, and the moist with the wind and rain; the sun and the moon move, one cold and one heat… Traditional Chinese culture is that men show strong attributes while women are restrained with soft attributes. In this process, the more talented and masculine men are, the more submissive and introverted women are. But this kind of female introversion does not mean neglecting women, on the contrary, meeting such a husband will make women’s talents more displayable. The lives of Mr. Qian Xuesen and Ms. Jiang Ying are probably the typical representatives of this.

Just imagine if Jiang Ying was just an excellent musician, who would remember her thousands of years later? It is precisely because of Qian Xuesen’s masculinity and compelling talent that makes Jiang Ying more beautiful and happier. You know, Qian Xuesen lived 98 years old first, and Jiang Yingnu lived 93 years old. Such an age is much better than that of a happy couple at noon in ancient times and modern times. They are the real hands of their sons and grow old with their sons.

7. Demand analysis

   As the main focus of Clipping is “light and easy to cut”, its core needs are potential creators and creative users with waist and head.

   1) Potential creators

• Features: Mainly watching videos, almost no videos, no video editing basis; focusing on popular videos, a large crowd base.
• Requirements: Use tools to add music and special effects to achieve basic editing functions; the software is simple and easy to learn and use, and the tool interface is not complicated. It is best to generate videos with one click.

2) Waist users

• Features: I like to use Douyin, and I am also keen to shoot short videos on my own; there is a need for short video editing, and I am willing to spend time editing the videos I have taken; do not meet the video editing function of the software; pursue entertainment and pay attention to popular videos.
• Requirements: The tool has rich and reliable functions, adding special video effects such as picture-in-picture speed change; learning current popular video templates and easy use; making advanced and beautiful videos, keeping up with popular trends, and enhancing the influence of your own videos.

3) Head user

The App Store scored 4.9 on the iOS App Store and 4.8 on the Android App. Analyzing the app market reviews in the past one month, the praise rate of 4 to 5 stars is as high as 78% on the iOS side and 93.5% on the Android side.

Based on the overall high app market rating of Cut Ying, it only extracts the core demands of users based on the 1 to 3 star reviews (330 pieces) on Android and iOS in the past month.

1) Bugs (stuck, crash, network anomalies, import and export anomalies) accounted for more than 60%

• iOS users pay more attention to issues related to adding new feature points and editing capabilities, while Android users pay more attention to issues related to update downloads, music editing functions, and text and letter editing functions.
• TOP issues for iOS users: performance category (38%), editing operation optimization (8%), increased function points (8%), frequent updates (6%), accounting for 60%+.
• TOP issues for Android users: performance category (33%), import and export optimization (10%), increase of function points (10%), update-related (9%) accounted for 60%+.

2) User insight

• Performance layer: The performance experience after the update needs to be paid attention to. Users often complain about the fast update frequency and the unsmoothness of some functions after the upgrade.
• Operation layer: Video editing capabilities have basically met user requirements, but there is still a lot of room for optimization of subtitle text editing functions and audio editing functions. At the same time, the operability of the video frame is also the core appeal of users.
• Capability layer: Adding anti-shake function, adding intelligent dubbing, templates and music browsing records are all reasonable function appeal points for users.

3) High-quality user reviews

• Can you add a function to rotate the video by ninety degrees, switch between horizontal and vertical screens, and cut out the extra screen.
• I hope that smart dubbing can be produced, and there is no starting point when adding a soundtrack. It is difficult to match the climax part of the video with the time-lapse video.
• Cut Ying is fully updated and repaired to make the sound quality better. The sound quality of Douyin is the same as that of Kuaishou, and the sound quality of the whole network cannot be independent. This must be optimized. In the production, as long as there is a point that is particularly good, it can automatically recognize the characters in the excision, and it is especially convenient to leave the favorite magnifier, which must be retained.
• It is fine to not compress the number of frames. No matter how many frames of video are imported, it becomes 30. If the problem can be solved, it will be five-star praise.
• Fun is fun, you can see it by yourself, but you can’t let people do tasks and make money. You have to recommend insiders to do tasks and make money. This is very hopeful. It’s not good at all, and there are more than one star. Gave it.
• I really want to vomit. I didn’t download Douyin, and I couldn’t jump when exporting the video. Then I actively saved it to the album. I saved it in the album before. I recently turned it over. What does it mean? It’s stuck, the music continues. There are one or two in the front of the picture, and there is nothing in the back. Then I thought it was too long, so I made another one, and it was still the same! No matter if it is posted on WeChat Moments or QQ, none of the videos are not music continuing, and there is no picture. Then go to the draft box, eh! It’s all right, I hope to deal with it.

In recent years, short video platform competition has intensified, and short video user penetration rate has reached a certain peak. In this context, how to retain users and enrich UGC content has become a core issue for future development. Ordinary video templates can no longer meet the needs of most users, and users are more willing to make videos more diverse through production techniques such as splicing and editing.

As a result, video production tools began to continuously develop and iterate. The video production App represented by Cut Screen, Quick Video, and Inshot meets the various needs of users when making videos to a greater extent, and facilitates users to create more creative and higher-quality video works.

According to Aurora Mobile (NASDAQ: JG) data: the penetration rate of the video production industry is 19.6%, and out of every 10 mobile phone netizens, 1.96 people have installed a video production app, represented by cut screenings, snapshots and draft designs , Video production App has shown a significant growth trend in terms of user scale.

In terms of growth trends, in 2020, the penetration rate of the video production industry will maintain a year-on-year growth rate of 71.1%-138.1%. The high growth rate can indicate that the video production platform has not reached its ceiling and has huge growth potential.

1. Product performance

   1) App Store ranking

   Based on the data of Qimai, it has been observed that the cut image has been relatively stable in the App Store total list (free) in the past three months, with an average value of 11. In photography and video (free) rankings have been ranked 2 ~ 3.

   Among them, on January 1 and February 14, 2021, the ranking soared to the first place in the overall list. It is estimated that because of the festive effect of New Year’s Day and Valentine’s Day, users need to use the cut screening to create special videos, such as “Review 2020″” Love everyday with lover”.

   

   2) Downloads

   Based on the data of Qimai, observing the download volume of Jianying in the App Store in the past year, it can be found that its download volume broke through the daily average of 40w and reached the highest peak on February 14-15, 2021, and the rest of the time was within the range of 30w-10w. Floating, the annual average value is around 15w.

   

   3) Changes in the number of monthly independent devices

   According to the iResearch Index, the monthly changes in the number of independent devices from February 2020 to January 2021 are shown in the figure. It can be seen from the figure that the overall growth state has shown a state of first decline and then rise. November 2020 is at the bottom of the valley, and the beginning of 2021 will rise strongly, with a year-on-year increase of 13.7%
