This is a basic requirement of officials in traditional Chinese political philosophy. Essentially it advocates the spirit of an official who does not abuse power to seek personal benefit, who works wholeheartedly for the public, who never shirks responsibility and is dedicated to service even if it requires self-sacrifice.

One should work to help the sovereign ruler in realizing his ideals, doing everything for the benefit of the country, without seeking personal wealth and honor. (The Book of Rites)
