First of all, make sure that your current CCB account is enabled to receive US dollars, and other procedures are the same as those transferred to Bank of China before. Generally, you can choose remittance purposes, such as service fees, living expenses, commissions, labor fees, tuition fees, gifts or others, but you must fill in the purpose of funds, otherwise the money will not enter.

I tried to transfer from HSBC to China Bank, and it usually arrives on the same day. CCB doesn't know, but it shouldn't take long, one day at most!
