Why was my ID card checked when I was playing in Kuanzhai Alley?

As long as you don’t do anything illegal or disciplined, it is routine for the police to check your ID card. Kuanzhai Alley is a national AA-level tourist attraction. It has been awarded the title of "Commercial Pedestrian Street with Chinese Characteristics" in 2009, a historical and cultural street in Sichuan Province, one of the New Ten Scenic Spots in Chengdu in 2011, and one of the ten most beautiful streets in Sichuan. In April 2018, the breathing tile wall in Kuanzhai Alley in Chengdu was transformed into a tourist sign-in wall. This attraction is a great place for leisure shopping.
