Is it better to be anonymous or not?

Anonymous. Well, according to the Law of People's Republic of China (PRC) on Public Security Administration Punishment, informants, witnesses, appraisers, translators and other personnel who assist the authorities in investigating illegal and criminal acts have the right to refuse to disclose their personal information such as their names and residences, and the public security organs will not pursue their legal responsibilities. Anonymity can protect your privacy and personal safety. Not being anonymous will lead to the disclosure of personal privacy and the security will not be guaranteed.
