The most direct way to find big brother in Tik Tok is to take the initiative, see big brother in other people's live broadcast room, write a few words to others and leave a message on the video. To tell the truth, this effect is very poor. At present, most of the eldest brothers are in the state of private messages, and the remaining eldest brothers who have no private messages don't know how many messages and private messages they will receive in a day. You may not have received so many private letters, but when you do, you will know. Eldest brother can't read these private messages at all, so the effect of doing so is very limited. Personally, I suggest that you should put more experiences on live content. This kind of thing, eldest brother should follow fate, calm down and wait for his arrival quietly.
