Found an article from 2017 where the Huainan Public Security Bureau Tianjia'an Branch organized an event on World Intellectual Property Day (April 25th) with schools as part of a campaign about the harm of illegal piracy and obscene books which is quite common on the internet. The event raised awareness of illegal publications, and respect for innovation and creativity.
Hilariously and unfortunately, this was one of the images that was used in the article for obscene books.
