Their training is so thorough, in fact, that they are even taught how to gain the “perfect smile.”
During the “how to smile” course in Dalian, Liaoning Province, China, customs police were made to practice by holding a “chopstick” between their teeth and smiling.
According to the Liaoning Customs Office the aim of the training was “to standardize officials’ amenity protocols and upgrade their receiving skills”.
As the picture shows, it is easy – just so long as you stick to the rules.
