Since 2004, Gong Xiuze has provided about 10,000 free haircuts(理发). He served people in need door to door. They include old people, disabled people and sanitation workers(环卫工).

Gong is 81 years old. He is a retired(退休的) traffic police officer from Taiyuan, Shanxi province. “I learned some simple but necessary skills of haircutting when I was young. I helped others cut their hair in the military(军队) between 1964 and 1968,” he said. After leaving military service, he became a traffic officer in Taiyuan.

After Gong retired in 2004, he found he had free time. “When I walked around in the parks in the city, I often found sanitation workers do cleaning work in the early morning,” Gong said. “They were really hard workers, and I wanted to do something for them.”

He wrote some notes and sent them to the workers. In these notes, he told them to visit him for a free haircut. He also gave notes to people who have difficulty moving. He promised to visit them and help cut hair at their home.

“I can feel my value of life at an old age while helping others in need,” he said. “I will continue the service as long as I can move.”
