The idiom "Heaven rewards diligence" in Ye Genyou's calligraphy means: Heaven will care for diligent people, and more efforts will be rewarded, which also shows that opportunities and inspiration are often only given to diligent people. "Heaven" means "Heaven", "Tao" means "advocacy" and "Heaven" means "God's will", which can be extended to objective laws. "Reward" can be interpreted as "realizing one's wishes", that is, reward is rewarded, and "diligence" means "diligence". In other words, "God will reward those who work hard". So generally speaking, it means that hardworking people will get more rewards. The Book of Changes says that "a gentleman is humble and a villain is blessed". The word "Tian" appeared in many pre-Qin books, mainly referring to "the law of nature", which is also explained in this way. "Heaven rewards diligence" has not yet found its origin. Perhaps "when you are full of losses and modest benefits, it is heaven" in Shangshu Dayu Mo is the closest. The original text is as follows: In the third month, the Miao people disobeyed orders. I boast Yu Yue: "Virtue only" for parents, guilt leads to anxiety. It only shows Gu Sou, Li Zhai Li, and I allow it. I feel very sincere, I have a seedling. "Heaven rewards diligence, tunnel rewards goodness, humanity rewards sincerity, business rewards letters, and industry rewards essence. This should be added later. Diligence can make up for it. " Tang Jingzong transferred Bai Juyi, the secretariat of Hangzhou, to Suzhou, the largest state in the southeast of the Tang Dynasty with complicated local affairs. As soon as Bai Juyi took office, he declined all banquets and devoted himself to government affairs. He quickly became familiar with the local situation, rectified the bureaucracy and won the praise of the people. He thinks that he is born clumsy and can only make up for it by diligence. In a word, God rewards those who work hard, and the opportunity is reserved for those who work hard. In other words, diligence can make up for the lack of talent.
