Why is Zhou Shuyi's number broadcast live by others?

There are two possibilities for Zhou Shuyi's number to be broadcast live by others:

1. Zhou Shuyi invited others to broadcast, probably to accumulate traffic.

2. In the process of live broadcast, Zhou Shuyi's live studio was temporarily banned because the scale of dancing was too large, and people needed to be invited to broadcast it.

All the above are speculations, and the specific reasons may need further official announcement or informed sources.
