The poem related to him is "I can only see that Wen Weng is vulgar, but I don't know that Li Guang has not sealed it." "Zheng Qian laughs at himself for poor drinking, and Li Guang is not old."

1. Du Fu's "Farewell to Jingnan" means that the world only knows that Wen Weng can change customs, but often forgets that Li Guang can't be sealed for life. Here, Du Fu took the opportunity of Li Guang's failure to seal the title of marquis to express his sympathy for his brilliant but not reused friend Li Jian.

2. "Zheng Qian laughs at himself for being poor and drinking, but why is Li Guang not old" in Lu You's Sleeping with Me means that Zheng Qian laughs at himself for drinking, while Li Guang is not as old as he is. Here, Lu You took Li Guang's failure to seal Hou as an example to express his views on life setbacks: there will always be setbacks in life, but the key is how to face them, whether to accept them calmly or to fight bravely.
