For those asking about Songsong,
The first picture is her weibo post when the team was announced.
The second picture was posted on September 14 at midnight or early morning. She wrote “明白离开的时候，纵然有千般万般的舍不得，也要舍得。” (I understand that if I leave that will be a lot of things I miss but I still have to give them up). The article captioned this is her luggage at the front gate of the national training centre. She will be leaving where she worked hard for long.
I think she deleted the post but some article wrote about it here
