In China, sexual behavior involving minors and adults is subject to strict legal supervision. According to the Criminal Law of the People's Republic of China and related laws and regulations, adults who have sexual behavior with minors may face legal liability regardless of whether they know the other party's true age. However, if an adult has sexual relations with a minor pretending to be an adult without knowing it, they still need to take measures to legally protect themselves. The following are specific suggestions: ### 1. **Understand relevant legal provisions** - **Criminal law provisions**: According to Article 236 of the Criminal Law and related provisions, adults who have sexual behavior with minors under the age of 14 constitute rape; and those who have sexual behavior with minors between the ages of 14 and 18 may constitute indecent assault or forced indecent assault or sexual assault, depending on the circumstances. - **Proof subject responsibility**: Adults have the responsibility to confirm whether the other party is a minor. Failure to fulfill the obligation of reasonable care may be considered to have constituted a crime. ### 2. **Take preventive measures** - **Verify the other party's identity**: Before establishing an intimate relationship, verify the other party's true age and identity information as much as possible, such as asking to see valid documents such as ID cards. - **Keep communication records**: Save chat records and communication records with the other party as evidence that may be needed in the future. - **Avoid meeting alone**: If you are not familiar with the other party, try to avoid meeting alone and choose public places to communicate. ### 3. **What to do if you find that the other party may be a minor** - **Stop the relationship immediately**: Once you suspect that the other party is a minor, you should immediately terminate any relationship involving sexual behavior. - **Collect evidence**: Save relevant communication records to prove your behavior and attitude during the relationship establishment process. - **Seek help from professional institutions**: Consult a lawyer or relevant legal aid agency to learn about specific response measures. ### 4. **If you are accused or encounter a legal dispute** - **Seek legal aid**: Contact a professional lawyer as soon as possible to obtain legal advice and agency services. - **Provide evidence**: Submit relevant evidence that can prove that you are aware of or have fulfilled your reasonable and prudent obligations, such as chat records, identity verification records, etc. - **Assist in investigation**: Cooperate with the investigation of the public security organs or judicial departments, provide true information, and strive to prove that you have no intention of breaking the law. ### 5. **Public education and self-improvement** - **Enhance legal awareness**: Understand and abide by relevant laws and regulations, enhance legal awareness, and avoid breaking the law due to ignorance. - **Enhance the ability to discern**: Improve the ability to discern the identity and age of others, especially in the online environment, and strengthen vigilance. ### Summary When adults establish close relationships with others, especially in the online environment, they should try to verify the other party's true identity and age to avoid unnecessary legal risks. If you find that the other party may be a minor during the relationship, you should terminate the relationship immediately and save relevant evidence for future use. When encountering legal disputes, seek professional legal help in a timely manner and safeguard your own rights and interests in accordance with the law.
