Who was the most incorruptible official in ancient times?

The most incorruptible official in ancient times was Harry.

Hai Rui (15 14- 1587) was born in Qiongshan (now Haikou) in Hainan. Famous officials in Ming dynasty. Harry experienced Zheng De, Jiajing, Qin Long and Wanli Dynasties.

1549 (in the 28th year of Jiajing), Harry took part in the provincial examination. He was first appointed to teach Chongqing in Nanping, Fujian, and later promoted to Chun 'an, Zhejiang and Xingguo County, Jiangxi. He carried out the policy of clearing taxes, rehabilitating false and wrongful cases and cracking down on corrupt officials, which won the hearts of the people. He has been promoted successively, and has served as a state judge, a minister of the Ministry of Housing, a minister of the Ministry of War, Shang Baocheng, an administrative officer of Gyeonggi, and an imperial adviser of Youdu. He cracked down on the mighty, dredged rivers, built water conservancy projects, urged severely punishing corrupt officials, prohibited taking bribes in private, and imposed whipping laws to force corrupt officials to return to the people, thus having the reputation of "clear sky".

Harry's incorruptibility is even inhuman. According to the official atmosphere at that time, when a new official took office and an old friend was promoted, someone would always send some gifts to congratulate him. As long as the amount of these gifts is not large, it is human nature. However, Harry publicly posted a notice saying that "being a court official now is different from privacy at home." Then return the gifts sent by others one by one, even the gifts sent by old friends He Bangtai and Shu from afar. As for the cheapness of the public, it doesn't cost a penny. Before Harry died, the firewood sent by the Ministry of War was seven yuan more, and he had to pay it back.
