As for the selection of Li Ning in the national feather industry, a very important reason is to support domestic products, which not only enhances the national pride of the Chinese people, but also enhances the brand influence. Since the Olympic Games last year, the Li-Ning brand has been on a meteoric rise. In addition to the acquisition of Kaisheng, which had previously sponsored the national youth team and the national youth team, its determination to enter the badminton world is still very obvious. At the end of last year, I participated in a market symposium held by Li Ning. Through the introduction of relevant personnel, I can believe that Li Ning is determined to build my country's leading sporting goods company. At the technical level, domestic well-known brands such as Kaisheng, Shengli, and Sopai are actually quite good. The strength and feel of the racket are actually not much different from YY, and even the mid-to-low-end ones are much higher than YY. Therefore, it is recognized by almost all the people. That is because its market operates properly, it is good at promoting itself, and it does not have many advantages in manufacturing technology. After Li Ning acquired Kaisheng, it still retained Kaisheng's brand, but the rackets sponsored by the national team this time must have come from Kaisheng's factory. There is no doubt about this.

As for the people I saw earlier using those copied slogans to talk about no version difference, good quality, and outstanding performance, these are just gimmicks to put it bluntly. No matter how high-end the racket is, no matter how advanced the nanotechnology, or the advanced WOVEN technology, the cost of manufacturing the racket will not be higher than 200 RMB. National players don’t even know as much about rackets as some enthusiasts. The difference in feel of the racket can actually be adjusted to a good state through their own superb skills. You can throw a racket that costs more than 200 and a racket that costs more than 1,000. Give it to them, and they can all perform at their usual training level. Therefore, when it comes to changing equipment, Guoyu’s daily training and competitions will not have any violent chemical reactions due to the change of equipment. This is just some promotional means for sponsors.

I hope my answer will satisfy you.
