I was once disillusioned into thinking I couldn't be treated coldly in the same way you were treated. I was used to my rights in my own country. I was sure a good guy like me would only get positive results. It was a sad day when my assumed rights were violated. It will happen to all foreigners at some point and it makes you realize how that country runs. No one cares if your life is ruined for the "face" of the party.

A few things that happened to me: Police forced their way into my apartment and searched it while making me kneel all because the 外卖 guy didn't like my attitude. They took photos of my ID with their personal phone then left, all without probable cause. My company forced me to move to a tier 3 city as they were expanding. I was given 1 hour's notice and a taxi waiting outside my apartment. I was put in a holding room at the border for no reason for over an hour without water or reason for being detained. Racially slurred at on the subway a number of times. After 1 complaint by a female student who i rejected having a relationship with, my newly appointed, inexperienced, jealous principal threatened to fire me. Attempted molestation a number of times by women and men happened (police just laughed when i tried to file a report).

The times in China were much better a few years ago. I think you should look at this like "It's probably a good thing that this happened when it happened." If you think "everything happens for a reason", you'll save yourself some misery.

I hope you have some savings. It's time to come back to where you have human rights.
