Chai Shengfang, born in July 1969, was a member of the Communist Party of China and the deputy secretary of the Party committee and magistrate of Lintao county in Gansu province.

During his eight years of service in Dingxi city, Chai, a Han Chinese, devoted himself wholeheartedly to the Party and the people, working for more than 12 hours every day. His selfless service left an indelible mark on each and every area of the two counties and one district that were under his jurisdiction.

Chai was so dedicated to developing the areas that he often worked through the nights. He proposed a focused poverty alleviation policy of "targeting specific households in five villages" based on his site visits and identified key industries for more than 300 villages in Lintao county to transform Lintao into a "provincial demonstration county for targeted poverty alleviation".

He always placed the common people and their livelihood first in any planning and was never afraid of taking responsibility. During his service in Lintao county, Chai visited almost all the administrative villages in the county and visited or met with nearly 5,000 persons/times, and did everything he could to solve their problems of water supply, traffic conditions, and access to schooling and medical resources.

On August 14, 2014, Chai began working at 8:05 am and didn’t stop until 1:30 am the next day when a long meeting ended, clocking a total of 17.5 hours. During the day, he met with several groups of visitors, studied the project of introducing Taohe River water to the central areas of Gansu Province, hosted the donations for schools commendation meeting, inspected the Beidajie renovation project of the county, and paid a field visit to Dongdajie to check the road conditions.

In the evening, he hosted the executive meeting of the county government at 19:30 and the meeting continued until 1:30 am the next day. A total of 53 items in 22 categories of government work were discussed during the six-hour meeting. In the morning, Chai suffered a heart attack due to stress and fatigue and passed away in his office. He was posthumously honored as "Model of the Times", "National Outstanding Communist Party Member", "Civil Servant to the Satisfaction of the Whole Nation" and other titles.
