（1） If you suspect that others are slandering you, you should pay attention to collecting evidence, such as the chat record of slander, published text, witness testimony, etc. （2） Specify the specific manifestations of the damage suffered by yourself, such as whether there is a change in the attitude of colleagues in the unit to yourself, a change in the style of social circles, etc., which can reflect the reduction of social evaluation, or whether you have mental abnormalities. （3） Try to communicate with the other party first, and ask them to stop rumor making and defamation. If the other party refuses, consider taking legal channels. Legal basis: Article 246 of the Criminal Law of the People's Republic of China stipulates that anyone who publicly insults another person or fabricates facts to slander another person by violence or other means, if the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention, public surveillance or deprivation of political rights. The crime mentioned in the preceding paragraph shall be handled only upon complaint, with the exception of those seriously endangering public order and the interests of the State. When the victim commits the act specified in the first paragraph through the information network and tells the people's court, but it is really difficult to provide evidence, the people's court may request the public security organ to provide assistance.
