An old friend of mine that I've lost touch with is Chinese. They lived in Europe for a number of years. When they couldn't get a new job their visa ran out and the went back home.
No problem getting a job. They had a place to live. Things were good.
But... When they left Europe they basically told their roommate, a student who was about 10 years their younger, that they were leaving and that's it. They abandoned the apartment. This left not only rent up to the student, but also the €300 fee of changing the name on the rental contract.
If a police investigation is launched against someone in China, you can be damned sure they will turn up something. If this influencer ever saw a doobie they will find out, and if they never did drugs they will find an acquaintance who did.
I say this because one day when my friend left work there was a car waiting. It was the father of her roommate. Turns out he was a "special" police officer. He told them to get in and gave her a folder. The folder had photos of them, their friends, even me. There were notes on the friends, SMS and social media exchanges. This included references to drugs. He took them to a bank, told them to take out the equivalent of €900 (he had their bank statements already) or their family would hear about this...and then he left them there on the street.
