Why are there negative competitions in badminton?

Hello! This can be divided into two problems.

1, China's number one women's doubles Yu Yang Wang Xiaoli deliberately lost?

There should be no suspense between China's Zheng He and South Korea's Zheng He. After all, as the number one women's doubles in China, the strength of Yu Yang/Wang Xiaoli is obvious, and they are also the number one women's doubles in the world at present. So this game will be an overwhelming victory for all fans at the beginning, especially for South Korea, which is not even in the top five in the world. However, the course of the competition was quite different from what was expected. The powerful China team frequently serves and touches the net, hitting the ball out of bounds. With so many low-level mistakes, it is obvious that they are going to lose. As another pair of women's doubles players in China, Ching Tien/Zhao, unexpectedly lost to the Danish team Wright/Peterson, in order to avoid the civil war between the two teams in the semi-final in advance,/had to lose the game to avoid the civil war starting in advance, which is also the direct reason why China's number one women's doubles deliberately lost.

2. What is the geometry of Korean women's doubles from being ready to lose to being helpless to win?

Of course, South Korea is not a fool. It has long been known that this pair of China have ulterior motives, otherwise they would have been abused by their strength. However, the last match was a "sharp decline" of Yu Yang/Wang Xiaoli, so in order to avoid the strategic civil war of women's doubles in South China, this pair of South Korea also began to compete who made more mistakes and was fast, which was also a positive "negative match". Naturally, everyone can see that both sides are so eager to lose the game, so the game director has to come in and warn the players not to play passively. But in the end, the Korean delegation gave up losing, not only because the China delegation was more eager to lose, but also because they had their own small plans. Since we can't avoid China's experience in advance, let's make a wedding dress for our teammates, because there are a pair of South Korean Hezhen/Min Rongjin, at least one of whom can go further.
