By exchanging RMB for foreign currency abroad, and then bringing the converted RMB back to China, foreign exchange and arbitrage transactions are realized. This kind of behavior is often called "underground money house".
Shekel is an illegal foreign exchange and arbitrage trading method, from which high profits are obtained. Because the shekel transaction is aimed at the legal loopholes in the foreign exchange market, it is illegal, risky and vulnerable to the attack of the regulatory authorities.
China's foreign exchange management policy has strengthened the crackdown on Shekel's behavior and issued a series of regulations to punish and punish Shekel. At the same time, the China government gradually expanded its open economic system, promoted the standardized development of the foreign exchange market, and fundamentally put an end to Shekel's behavior.
