How did Sima Yi's tomb tiger, Zhuge Liang's Wolong and Wolong come from?

Zhuge Liang lived in the southern suburb of Yang Du (now yinan county) in Xuzhou. This place is famous for its precipitousness, with two mountains on both sides. The gap between the two mountains looks like a dragon in the distance, and Zhuge Liang lives here, so this is one of the reasons why Zhuge Liang is called Mr. Wolong.

Another most important reason is that Zhuge Liang read poetry books from an early age, knowing astronomy above and geography below. Zhuge Liang also traveled all over the country in his spare time to observe the sufferings of the people and find ways to change this phenomenon. Politically, he has strong management ability, can sympathize with people's feelings, and has strong governance assistance ability on the basis. Zhuge Liang can predict the change of the weather by observing the stars, so he is very sure of the predictability of the weather. He also recorded the geographical features of all parts of the world during his travels, and gained a certain understanding of where to ambush and where to fight. Zhuge Liang was talented and lived in a strange terrain like a dragon, so Zhuge Liang would be called Wolong by the world at that time.
