Waiting for a rabbit means: the original metaphor is luck to succeed without effort. Now it is also a metaphor for sticking to a narrow experience and not knowing how to change it.

original text

There were plowmen in the Song Dynasty. There was a plant in the field. When the rabbit touched the plant, its neck broke and it died. Stand by and watch because you released this plant, hoping to get the rabbit back. Rabbits can't be recovered, but as a small fruit of a song. Today, the people who want to go to the former dynasty are all guarding their factories and so on. -from "Everything is wrong, five mistakes"

There was a farmer in Song State, and there was a stump in his field. One day, a rabbit running fast ran into a stump, broke its neck and died. So the farmer put down his farm tools and stood by the stump day and night, hoping to get another rabbit. However, the hare could not get it again, and he himself was laughed at by the Song people. Now I want to use the past policy of governing the country to govern today's people, and I am as wrong as waiting for him!
