A group of students at the Huazhong University of Science and Technology have helped families find their loved ones.

The volunteer team of students has been helping many parents look for their children by restoring (恢复) over 1,000 photos. The team was set up by Sheng Jianzhong four years ago. He first thought to restore photos of missing children when he saw a missing child notice with a poor-quality image (劣质图像) in 2020. He wanted to help the parents restore their images. With the clear photos, the parents can post them on the Internet to find their missing children. But it cannot be completed by one person alone, he needed a team. Luckily, many students volunteered to join in Sheng’s project.

In December 2021, father Sun Haiyang finally found his son after 14 years of searching. Sheng’s team played an important role in finding the boy, and Sun expressed his thanks to them when they met. It has helped 11 missing children find their families—nine in 2022 and two in 2023.

Sometimes the families don’t even know the team’s help. “But we are happy for them,” said Zhang Shaoyun, a member of the team.

In the future, Sheng plans to build a better team to run the program. “It would train more young people to work for good causes,” he said.
