Send more than 30 text messages and make more than a dozen phone calls a day. Life and study are seriously disturbed. Is it annoying? Can I file a civil lawsuit?

Judging from what you said, this kind of behavior has violated the provisions of Item 5 of Article 42 of People's Republic of China (PRC) Public Security Administration Punishment Law, and is suspected of "sending information to interfere with normal life". You can report the case to the local public security department and demand that such illegal acts be dealt with according to law.

After the public security organ makes an administrative punishment, it may also bring a civil lawsuit to the people's court, demanding that the offender compensate the losses according to law.
