Yu was always seen patrolling with tiny dolls hanging from his uniform, offering them to crying children and guiding patients' families.
"I see doctors and nurses busy every day, and parents are worried about their sick children," said Yu Jingjing, the security guard. "I am happy to do something within my abilities to help ease the anxiety of parents and children during their hospital visits."
Yu has become a sensation at the children's hospital. In addition to the two or three dozen dolls attached to his uniform, he also wears a small red sign that reads, "Please call me if you need help".
