The first part comes from Mencius wholeheartedly: "I am worthy of heaven, but I don't care about people." It means to be upright and open-minded, hold your head high and be worthy of the sky, bow your head and be worthy of others, and never do anything wrong to others.
The second couplet comes from the preface of Fan Ning's biography of Spring and Autumn Valley Liang, a Confucian scholar in the Eastern Jin Dynasty, and praises Spring and Autumn: "A word of praise is better than a national gift; The slanderous words of the film have insulted the market. " It means that a compliment is more than a dress given by the king.
