Forget the swear words, actual slurs get used lol. I hear my parents casually use the term "低B" (its equivalent of the r-word) or "傻仔" when refering to autistic people or people with Down Syndrome. There is zero Political Correctness, its so fucked. You have a slight depression issue and its suddenly shameful. These things are hidden from statistics so they seem rare, but yet every village seem to have a few of those people. They get treated so badly. Socially ostricized. Everyone talks about it like "Did you hear about their family, their kid is a 低B" on phone call gossips. And with One Child Policy, if their first child is a son, they couldn't have another child*, so their bloodline is dead, they can maybe apply to get permission from the government to have another child, but it could be too late, fertility issues with old parents, you know... so the parents are shunned. The kid will never be allowed in a "normal" school. Universities kick students out after they got accepted, because they found out about their autism diagnosis. No "ADA" equivalent. So cooked.

(*For context, in rural areas, if the first child is female, they can apply for permission to have another child, two is the absolute max limit, even if their second child is female, that's it. If first child is male, that's it, no more. Its patriarchy basically, male-preference in society)
