Why is tiger leaping gorge called tiger leaping gorge?

Legend has it that Master Mu, the ruler of Lijiang at that time, was extremely rich and surrounded by talented people. One of them can tell a fortune. One day, I calculated it for Master Mu. It is said that Master Mu was rich when he was born, but there was no coffin available after his death. Master Mu was frightened. From then on, wherever he went, he put a coffin every ten miles to fight against his fate. One day, when the weather was fine and Master Mu was in a good mood, he rode his mount, the tiger, and walked along the Jinsha River. The river is surging and picturesque. When the tiger came to a narrow reach, he jumped on a big stone in the middle of the river. The tiger went ashore, but people never went ashore with the tiger at the same time, but fell into the rolling river. Time has passed, Master Mu and his tiger have long been lost, but they have left imaginative names such as Tiger Leaping Gorge and Tiger Leaping Stone to future generations.

Please adopt it. Thank you.
