As far as Shangshu is concerned, there is a saying that "Heaven rewards diligence". Han Yu once wrote an inscription "Heaven rewards diligence" to encourage future generations.
The word "Tian" first appeared in Shangshu and appeared in many pre-Qin books. Mainly refers to the "laws of nature", which is also explained in this way.
The original source of "Heaven rewards diligence" has never been found. Perhaps the "full loss, modest benefit, time is heaven" in Shangshu Dayu Mo is the closest, and the original text is as follows:
On the thirtieth day, the Miao people disobeyed their orders. Yi praised Yu and said, "Only virtue can move the sky, and there is no room for progress. When your mind is full of losses and modest gains, it is heaven. When the emperor first set foot in Lishan and went to the fields, he cried and cried, ashamed of his parents. I only saw Gu Sou and osmium. "
Heavenly rewards, authentic rewards, human rewards, commercial rewards, and industry rewards. This should be added later.
