Is it illegal to send a financial text message saying door-to-door collection?

Legal subjectivity:

The purpose of collecting loans is to prevent the expiration of the statute of limitations and thus the loss of the right to win the lawsuit. Legal objectivity:

Article 245 of the "Criminal Law of the People's Republic of China" Whoever illegally searches the body or residence of others, or illegally invades the residence of others, shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention. Judicial personnel who abuse their powers and commit the crime in the preceding paragraph shall be severely punished.
