Yes, you have to look at the selling price. All transactions above the bid price are relative to the bank. You want to buy Japanese yen, that is, you buy Japanese yen from the bank with RMB, that is, you sell Japanese yen relative to the bank. The selling price has nothing to do with the spot cash price.

The buying price means that the foreign exchange you hold needs to be converted into RMB from the bank. Compared with banks, it is to buy foreign exchange and pay RMB. Cash refers to foreign currency cash, and cash refers to foreign currency remittance and electronic bills (such as promissory notes and checks) issued by foreign banks. Because the convenience and liquidity of cash are more convenient than cash, it can be directly transferred to the bank without physical transportation, storage and interest loss, so the purchase price of cash is a little higher than cash, that is, cash is more valuable than cash.
