Idioms and allusions
Zhuangzi's lieyukou, written by Zheng lieyukou in the Warring States Period: Zhu Jiman learned to kill dragons in zhiliyi, a family of thousands of gold. Three years of technical success, but no use of its clever. Once upon a time, Zhu mang wanted to learn a unique skill that no one else could, so he sold off his property and went out to learn from his teacher. Three years later, when he came back from school, he introduced how to kill the dragon. Everyone envied him very much. The children asked to see his dragon killing sword. An old man said that although his dragon killing skill was good, there was no dragon to kill at all. Then Zhu realized. implication a good skill or technology should fit in with the environment at that time. If it is separated from the environment, no matter how good the technology is, it seems meaningless at that time. In other words, if the environment changes, its role can be reflected.
