Why did Lin Zexu change Shen Baozhen's poems? What do you understand from it?

Lin Zexu was a national hero of China's anti-smoking movement in Qing Dynasty. He had a talented and handsome daughter who married Shen Baozhen, who was quite talented at that time. Shen Baozhen is youthful, boastful and supercilious.

Lin Zexu changed his poems to inspire his son-in-law

Shen Baozhen, son-in-law of Lin Zexu, was not famous when he was young, and was full of ups and downs. She once sang a poem about the new moon: one hook is enough for tomorrow, why is it full of splendor? After reading it, Lin Zexu thought his son-in-law's poem was good, but there was something wrong with it, so he changed the word "must" to "love" for him. Shen Baozhen's poems are somewhat conceited and narrow-minded. Lin Zexu changed it to "what's more, it is full of ten points", which is quite different in poetry. When you become a fame, you can accumulate talents and knowledge for the world to use. Once in a high position, you can show your talents and realize the great cause of governing the country and safeguarding the country. Moreover, compared with the previous sentence, the poem implies the profound meaning of "worrying about the people if you live in a high temple, and worrying about the monarch if you are far away". The word difference reflects the different thoughts of Weng Xu and his wife.
