Why is there no book in Zhou Yu's study, and Zhuge Liang says there is one more than him?

The problem you mentioned seems to have been mentioned in the TV series "New Three Kingdoms" filmed a few years ago, right? Has it been elaborated in the plot? Didn't notice? It doesn't matter. Let me describe it again.

After Zhuge Liang crossed the river with Lu Su, he first met with Sun Quan, and then met with Zhou Yu after returning from a business trip in other places, and skillfully used Cao Zhi's "Blue Bronze Quetai" to motivate Zhou Yu to make up his mind to resist Cao. Later, Zhuge Liang stayed in Soochow and became a member of the alliance. When we met at the weekend, he mentioned the problem of books in the study.

Zhou Yu said that I burned a book after reading it, so there were no books in the study. I mean, I'm knowledgeable and have a good memory.

Zhuge Liang laughed and said that Gong Jin and I have the same habits. What a coincidence, but there is a book in my hut that I can't burn. Zhou Yu was surprised and asked what book it was. Zhuge Liang said it was the Gregorian calendar (that is, the calendar we are talking about now) because he lived in the wilderness and deep mountains. If there is no longer a Gregorian calendar to record dates, wouldn't it be the sun and the moon?

Zhuge Liang said this, in fact, to be humorous and ease the atmosphere. Of course, he is also a little flattering to Zhou Yu, trying to explain that he is still a little worse than Zhou Yu. After all, the two sides are allies and the relationship is too stiff, which is not conducive to the follow-up work; But at the same time, it can't be too explicit, so books that are said more are almanacs.
