It will undermine the fairness, justice and transparency of the market and harm the interests of the majority of investors. Therefore, these behaviors must not be adopted. The following are some common illegal market manipulation methods: 1. **Wash sale manipulation**: that is, the perpetrator continuously trades his own securities to create the illusion of active trading and induce other investors to follow suit. 2. **Relative entrustment manipulation**: colluding with others to conduct securities transactions with each other at a pre-agreed time, price and method to affect the securities trading price or securities trading volume. 3. **Continuous trading manipulation**: By concentrating financial advantages, shareholding advantages or using information advantages to jointly or continuously buy and sell, manipulate securities trading prices or securities trading volume alone or in collusion. 4. **Deception trading manipulation**: Fabricating and disseminating false or misleading information to influence investor decisions and manipulate securities prices. 5. **Preemptive trading manipulation**: Taking advantage of the convenience of office to trade before other investors know or use important information to obtain improper benefits.
