Why didn't China Bank receive foreign exchange in February 16?
February 16 is a normal working day. If your foreign exchange is remitted to the Bank of China, there is no problem of not receiving it. There are two situations. First, the bank received it, but it didn't help you get in. Second, foreign exchange has not been remitted to the bank. You can ask the bank to help you find out where it has been remitted, but this service usually costs money.
