I will share my experiences of visiting the police station twice, both were normal matters,
not involving any illegal activities,

1. I posted a tweet about a foot masseuse who looked like Dilraba Dilmurat, and then that tweet went viral. Subsequently, Dilraba's fans reported me to the police, and I was arrested,
accused of disturbing public order,
I was taken to a detention room for 24 hours, went through the whole process, fingerprinting, urine test, voice recognition, and photos...
Because I had a good attitude of admitting my mistakes, I received no punishment, only required to write a guarantee letter promising not to post such things again.
I won't talk about the treatment I suffered inside, and afterwards I didn't dare to file a complaint because I was afraid of retaliation.

I can only say that once you are inside, you have no human rights; they will trample your dignity underfoot,
even if you are not a suspect,
uh, I didn't even commit a public order offense, and they treated me this way.

2. I tweeted about the Mid-Autumn Festival in Chengdu, saying I was looking for three male fans to spend a pleasant evening with,
and then I was arrested.
The police went to the hotel where I was staying but couldn't find me, so they called me, and I went there myself.

Only upon arrival did I realize that the police suspected me of engaging in public indecency. I repeatedly emphasized that I am not gay, just making a joke, really not gay,

At that time, they planned to detain me, but I had just had a tooth extraction and was bleeding in my mouth, so I couldn't go in, and they just made me write a guarantee letter stating that I wouldn't engage in public indecency or look for prostitutes online, and then they let me go.

Regarding the first incident, I was in the detention room for 24 hours, sigh, I won't talk about it, and I can't say more.
