Rotten horse
It's an idiom to describe the danger of overturning.
Shiyi uses rotten ropes to drive a galloping horse. The danger of overturning is very serious. It's more about fear. Also known as "corrupt rope Royal horse." It is from the song of five sons in the book of history: "to Lin Zhaomin, you are like a decadent Suo who controls six horses."
