Don't hang contact information in the live broadcast room. Hang v in the short video. The video will not pass the review and even face the risk of title. The same is true of the live broadcast room. If you often hang up the contact information, the light person will limit the flow, and the heavy person will be banned.

At present, only WeChat Live can hang V in the live broadcast room. Wechat live broadcast develops private domain traffic. With the big platform of WeChat, there is no limit to promoting QR codes in the live broadcast room.
