The chinese cant fight
As someone who watches a lot of fight sports and know basic history, I feel that the Chinese for some reason cant fight. In fight sports like MMA, kickboxing, boxing, wrestling you can definitely see trends between different ethnicities and races. Some being more athletic, some being more aggressive or durable, and some inbetween.
Koreans, Filipinos, and Japanese (like Mexicans) are known in fight sports for their toughness and durability (especially the Japanese) but the few Chinese fighters there are they have not shown much heart and they are never very durable. (Zhang being the exception in one of her title fights).
Often times they have a massive skill advantage and still manage to lose to a lesser braver fighter. They have a massive population they should have more fighters.
Also the recent history of China they do not have much war experience and when they did go to war they got smashed. They intimidate people militarily but never really do anything. Is it just a coincidence? Why are asians known for being so tough but the Chinese are not?
