Did Guo Moruo write the word "Lu" in the two "Zhuge" wrongly?

Guo Moruo mentioned that Lu is not a typo in Hengyang and Nanyang, but as calligraphers, they all have their own writing habits, so it is normal to write more and less, because after all, they write cursive or official script instead of standard regular script, so these are understandable.

You should know that Guo Moruo is an archaeologist and has made great achievements in literature. It is unlikely that he will casually write typos on the plaque of a cultural relic. Moreover, if a single plaque is misspelled, this possibility is still relatively large. It just happens that the same word is misspelled on the plaque in two places, so the possibility of this situation is very, very small. Moreover, we should know that the plaques in these two places are different, one is simplified Chinese characters and the other is traditional Chinese characters, so there are mistakes in both cases, which reduces this possibility.

Guo Moruo wrote simplified characters in Nanyang, probably in the 1970s. He wrote from left to right, and he also wrote his name horizontally at the place where he signed, because simplified characters became popular in the 1970s. So at this time, the words he mentioned followed suit, and there was a horizontal writing and simplification.

We should know that only regular script is considered as the standard font in our daily writing, so some calligraphers usually write on various plaques in cursive or running script. These people like to write fonts that reflect their personal style. Then at this time, they will more or less highlight their personal characteristics through painting, so as long as they are not regular script, they don't have to care too much about whether a certain part is standardized.
