Some people say that when Guo Moruo wrote an inscription for Xiangyang Longzhong, he deliberately wrote the word "Zhu" wrong. Why?

1 It is rumored that Guo Moruo wrote an inscription for Xiangyang Longzhong that year? Zhuge Cao Lu? As a calligraphy tablet, will you? Zhu? This word is deliberately misspelled. Write one more line and it will become two lines. In fact, this is a far-fetched statement.

2 Guo Moruo wrote it for Xiangyang Longzhong? Zhuge Cao Lu? A plaque? Zhu? That's true, but? Hey? Chinese characters are really misspelled (see attached label), but they are not found. A specious word that you may often fail to write is forgotten at the beginning, which is normal, but there is something wrong with this word!
