Armed police can seem rather aloof and intimidating, but a woman was captured reaching out to one of them in a warm moment this May Day holiday.

The armed policeman was on sentry duty at the Terracotta Warriors museum in Lintong city, Shaanxi province on Saturday. It was a hot day and he had sweat all over his face. According to regulations, armed guards cannot move while standing guard.

A young tourist walked past him and noticed his difficulty, and took out a napkin to wipe his sweat as a gesture of gratitude for his service.
