When will the china mainland test location online?

I saw that all of the china domestic test location is off-line, only HK exist.
In some case , we need the china mainland test location to test network quality in china.
I remember there are ShangHai and JiangSu test location in page before.
So could I know the reason of the location off-line?

Hello, join to @yonggang_gu question. I’m highly interested in tests within China. Please answer why all locations are off line. Best Regards
