Hi, let me explain Chinese society to you. China has a serious problem in terms of shortage of women(one child policy), so many horny Chinese men used to travel to Vietnam, and other surrounding East Asian countries to practically buy a bride but since the whole Pak-China ''friendship'' scam, our government is giving out visas to these horny men like gulab jaman so that these men can now target Pakistan women, but our culture is quite conservative, sooner or later one of these clowns are going to end up underneath some angry Pakistani's boots for tricking their women and then selling them to prostituting in China.
This documentary should give you a better insight into broken Chinese society as its government obviously does not allow free speech.
