China's laws do not explicitly stipulate that it is illegal to watch and browse obscene articles, but only stipulate that it is illegal to make, transport, rent and disseminate obscene books, periodicals, pictures, movies and audio-visual products. The law can be done without prohibition. In my opinion, it is not harmful to society, so it is not illegal.
Legal basis: People's Republic of China (PRC) Criminal Law.
Article 364 Whoever disseminates obscene books, periodicals, movies, audio-visual recordings, pictures or other obscene articles, if the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than two years, criminal detention or public surveillance. Whoever disseminates obscene articles to minors under the age of 18 shall be given a heavier punishment.
Article 366 Where a unit commits the crimes specified in Articles 363, 364 and 365 of this section, it shall be fined, and the persons who are directly in charge and other persons who are directly responsible shall be punished in accordance with the provisions of these Articles.
