Origin of Idiom: The idiom "Remembering a horse is hard to chase" originated from Zuo Zhuan. Zuo Zhuan is a historical document in ancient China, which records the historical events of Lu in the Spring and Autumn Period. The specific source of idioms is the story of Dr. Zi Ya of Lu. According to legend, Ziya escaped from the encirclement and suppression of Lu by Xu's express train, which made Lu's pursuers unable to catch up with him. Thus came the idiom "it is difficult to catch up with a carbine", which is used to describe the situation that it is extremely fast and difficult to catch up.
Usage example: This idiom can be used in various occasions, as shown below:
Things or people that are extremely fast, such as a racing car, a runner, or a rapidly developing technology industry, can all be described as "a comeback is hard to catch".
Describe the fleeting opportunity: sometimes, once an opportunity is missed, it is difficult to seize it again, just like a horse flying away. In this case, it can be said that the missed opportunity is hard to recover.
Describe the ability or achievement of a person or thing: If a person or thing performs well in a certain field and surpasses other people or things, it can be described as "recalling the past".
Similar Idioms: Idioms like "It's hard to catch a comeback" include "Take the lead" and "unstoppable", all of which emphasize the unstoppable speed, strength or advantage.
Summary: "It is difficult for an old horse to catch up" is a vivid idiom, which refers to the situation where the speed is extremely fast or the opportunity is short in the scene where the horse-drawn express train is difficult to catch up. This idiom is widely used in Chinese to describe various situations and emphasize the importance of speed and superiority. No matter in life or in literary works, "comeback" is a very expressive word.
