Legal analysis: 1. Use China's current account convertibility to enter the China market. We can use false import and export prices, advance payment, deferred payment of foreign exchange, parallel loans, and wrong foreign debts in advance.

2. Take foreign-funded enterprises in China as the channel. First, through the establishment of investment companies or production subsidiaries or joint ventures in China, or in the name of joint ventures or wholly-owned projects, in the form of registered capital or capital increase of enterprises, foreign exchange can be collected and settled from abroad.

3. Through shareholder loans of foreign-invested enterprises, that is, foreign-invested enterprises make short-term foreign loans and settle foreign exchange in the form of shareholder loans. Through the cooperation between domestic foreign-funded enterprises and overseas affiliated enterprises, it is convenient for overseas funds to enter China by temporarily collecting the payable funds.

4. Ways to inflate trade. At present, Chinese enterprises implement compulsory settlement and sale of foreign exchange for import and export. Therefore, if foreign currency is converted into RMB to enter China, foreign trade enterprises in China can falsely report their exports, thus raising the prices of export commodities and issuing high export invoices. In this way, a part of foreign currency can flow into China through export trade.

Legal basis: Article 6 of the Foreign Investment Law of People's Republic of China (PRC). Foreign investors and foreign-invested enterprises shall abide by the laws and regulations of China, and shall not endanger China's national security or harm public interests.
