At about 10:50 a.m. on September 22, the customer service desk of Tangshan Hengmao international city management office received a phone call from the owner saying that his child's leg was stuck in the leisure seat in the park, hoping to get help. The engineering master rushed to the scene and found that it was a boy of two or three years old whose thigh was stuck in the gap of a three person leisure chair. The boy's parents are comforting the boy at a loss.

After checking, the little boy's leg was not hurt. The engineer appeases the child while checking the situation. In order to prevent the boy from being hurt for a long time, the engineer decided to disassemble the seat with a screwdriver. As the seat parts were disassembled one by one, after a few minutes of hard work, the boy finally got out of trouble. After examination, the boy's right leg was not injured. His parents repeatedly expressed their thanks to the engineering master.
