Foreign currency exit permits can be handled in banks, and the handling fee for each permit is about RMB 10 yuan. Carrying cash can be used for payment immediately, with low cost, but it is neither convenient nor safe. Once the cash is lost or stolen, it cannot be compensated. Therefore, in addition to carrying a small amount of cash, it is best to send large amounts of foreign currency by remittance.
Extended information All major domestic banks have launched international credit cards, either with both RMB and specific foreign currency accounts, or with specific single foreign currency accounts, which can be used abroad. Some banks have also specially launched credit cards for international students, which can basically provide rich currency options for major countries and regions studying abroad.
Therefore, if you need to carry more foreign currency funds, you can consider depositing part of it into a credit card. However, it usually takes some time to apply for a credit card, so you should apply in advance.
