What are the main reasons why toddlers in Handan climbed back to Yan State?

Because he not only didn't learn the walking posture of Handan people, but also forgot his original walking posture and finally had to climb back.

Zhuangzi Qiushui records that during the Warring States Period, a young man from Shouling, Yan State (now Luoning County, Henan Province) went to Handan to play and found that people there walked beautifully, so he followed suit.

As a result, instead of learning well, I forgot how to walk before and had to climb back to my hometown. This story gradually evolved into an idiom, which means blindly imitating others and forgetting one's duty.

Extended data:

Li Bai once wrote the poem "Antique": An ugly girl will do something and surprise her neighbors. Shouling lost his step and laughed at Handan people. There is a "pedestrian bridge" on the Qinhe River in the old city of Handan, which was built in the 45th year of Wanli in the Ming Dynasty (16 17) and is a seven-hole stone arch bridge.

Although "step" in this idiom is mostly interpreted as "step", there is also a saying of "dance step". It has also become a topic of discussion for many experts and scholars whether to learn "walking" or "dancing" in Handan.

Some modern scholars, after careful textual research, think that what they learned in the story of learning to walk in Handan is actually not the walking posture of ordinary people, but a very popular dance step in Handan, the capital of Zhao State at that time.

This dance step is called "jump" (read some western words), which is similar to the tiptoe dance of modern western ballet. It is very beautiful. The original intention of the story may be that I didn't learn the dance well, or even forgot my original dance skills.
