Second, there is a super community in Weibo. You can pay attention to the super-star community and see if there are any like-minded people who can talk to you ~
Third, Weibo also has Ying Yuanhui fans. You can join first, then look at the diving fans, and then chat privately ~ so you have one more comrade-in-arms ~
