A special activity took place in Deda Yuyuan Community, Dezhou City. The community’s property management (物业管理) organized a weight-loss event, which concluded on December 1st. It was their first time holding such an activity, and it gained great popularity among people.

The event opened registrations (登记) on September 1st, 2025. Families in the community could have one member, aged 18 to 60 for men and 18 to 55 for women, take part. The rule was simple: for every 0.5 kg lost, participants could get 30 yuan off their property fees.

Over 200 people signed up, and 126 of them persisted until the end. Together, they lost a total of 1,050 jin (1 jin = 0.5 kg), saving more than 30,000 yuan in property fees. The champion was 36-year-old Zhang Qi, who lost 25.2 jin and saved 756 yuan. He was happy to win and became an inspiration in the community.
