One of the most popular games in China is testing age verification using facial recognition. Specifically, it is Honor of Kings, a game with over 200 million registered players. This verification is to help you adhere to the set time limits per day. In July 2017, in China, the playing time for all players under the age of 12 was limited to 1 hour per day, and for players between the ages of 13 and 18, the limit was then set to 2 hours per day. These rules are intended to help in the fight against addiction.
