It is illegal and unethical for corrupt officials to try to use legal loopholes to protect their illegal gains, but they may resort to the following means: 1. **False accounting operations**: By falsifying financial records, fictitious transactions, and concealing income, they attempt to confuse the flow of funds and make it difficult to trace and identify their illegal gains. 2. **Transferring assets**: Using complex financial arrangements, such as setting up accounts abroad, investing in hidden projects, and transferring assets through affiliated companies or relatives, they launder and hide illegal funds. 3. **Abuse of power to interfere with investigations**: Relying on their position in the power system, they attempt to hinder the normal conduct of judicial investigations, such as interfering with evidence collection and putting pressure on investigators. 4. **Exploiting loopholes in legal gray areas**: Taking advantage of the lack of clarity or gray areas in certain specific circumstances, they attempt to find far-fetched excuses or evasions for their own corrupt behavior. However, the legal system has been continuously improving and strengthening, and law enforcement and judicial organs will also use various professional means and measures to combat corruption, identify and dismantle these attempts of corrupt officials, and finally make the offenders receive the legal sanctions they deserve, and the illegal gains will be recovered according to law. Any attempt to evade the law will ultimately fail.
