Contact your domestic issuing bank first to determine whether the money has arrived at the domestic head office or local branch of the issuing bank. If the funds arrive in China, things will be better handled. You only need to contact the relevant department of the domestic issuing bank to transfer to an account that can accept foreign exchange. For details, please call the local branch of the issuing bank for customer service consultation with relevant departments.

Another possibility is that the money hasn't arrived in China yet, and it may change careers in China or other circumstances. At this time, you need to wait first, or ask your friends to check the current location of the money through the local post office.
