The Communist Chinese would not allow that many people to leave for no reason.

Bingo. Most are military aged males. They were sent here on a mission.

IMHO one reason is the shortage of young available women in China (due to sex selection/one child policy). In other words, China has a bunch of expendable military aged men while other young men stay home and help make babies (to aid with China's aging population).

I think China is playing the long game here and keeping their options open. If China thinks a situation in the future is worth using these young men to militarily attack us, the men are here and ready. If China wants to keep slowly undermining us drip-by-drip with even more Intellectual Property theft -- the men are here to do it. If China wants to further undermine our middle class by having Chinese men here to work blue collar jobs for less - the men are here to do it. All while the men know that their families back home are under the CCP thumb and need good social credit scores and don't want to be put in gulags.
