If the black market of foreign exchange is prosperous, the exchange price is similar to that quoted by banks, but it depends on the quantity. Guilin is a good example. You can exchange foreign exchange at a very low price. There are many foreigners and foreign exchange.

Such people will not care too much about the price difference, and the price difference will not be too outrageous.
