Restaurant employees in northern China were filmed crawling along a square as part of a training exercise on July 22.

The video, shot in Harbin City in Heilongjiang Province, shows dozens of staff kneeling down and crawling around a parterre.

According to reports, some citizens tried to stop them and had an argument with the restaurant manager.

The manager, named only as Li, reportedly said that they undertook the activity in order to inspire their employees and that it was part of a training exercise.
