As we all know, foreign exchange business has been strictly controlled by the state, and buying and selling foreign exchange must be carried out in designated foreign exchange banks, China Foreign Exchange Trading Center and its sub-centers or institutions with foreign exchange business qualifications. Enterprises or individuals engaged in buying and selling foreign exchange privately, buying and selling foreign exchange in disguised form, or buying and selling foreign exchange in reverse shall be given administrative punishment by the foreign exchange administration organs. If the circumstances are serious enough to constitute a crime, criminal responsibility shall be investigated according to law. Therefore, if an enterprise or individual conducts foreign exchange transactions with non-governmental organizations without foreign exchange business qualifications, it is likely to be identified as illegal foreign exchange trading. When the exchange amount reaches a serious level, it is likely to be convicted of illegal business operation and investigated for criminal responsibility. Therefore, when enterprises and individuals need to exchange foreign exchange, it is best to exchange foreign exchange at designated foreign exchange banks and financial institutions with foreign exchange business qualifications. If the staff of relevant institutions take the initiative to inquire about foreign exchange matters, it is best to check their business licenses or industrial and commercial registration information in advance to see if they are qualified for foreign exchange business before exchanging with them. Don't trust each other's sweet words, lest you get into trouble.
