There is only one way: when purchasing Century Internet O365, define the part after the administrator's default account number @ as @xx-my.partner.onmschina.cn, which is called sharepoint master station.

After purchase, the address of the sharepoint site you create can only be in the following format:

& lt the above custom fields >: .sharepoint.cn/sites/< Your own defined fields >

For example, our company's O365 website is o365online.cn, and our sharepoint main station can be defined as o365online.sharepoint.cn, while the sharepoint site used for training or other purposes can only be defined as o365online.sharepoint.cn/sites/training..
