I didn't know Fan Deng at first, but when I was playing Tik Tok, this man's preaching videos often appeared, which made me feel bored. I spent a whole day's work playing Tik Tok in my spare time instead of listening to others give me lectures. I blacked out all the accounts that appeared, but they continued to appear, so that my blacklist included more than 20 accounts for studying in Fan Deng. So one day I searched "Fan Deng" in Tik Tok, and there were probably more than one hundred such accounts, which I couldn't pull myself. I saw from his comments that Fan Deng was called "the poison of Tik Tok". Sometimes it's because this person wants to uninstall Tik Tok.
