Hong Kong has no foreign exchange control. It is an international metropolis, and all kinds of currencies are free to enter and leave. Moreover, Hong Kong companies have low taxes and do not have to pay taxes, so many people use Hong Kong companies to collect foreign currency.

Some people need to change foreign currency into RMB, while others need to change RMB into foreign currency. You can ask friends who are engaged in foreign trade and import and export for help. If the amount is not large, just transfer it directly to China (50 thousand dollars per person a year). There are many ways, but some will deduct the handling fee. I hope I can help you! ! !
