" A thousand-year-old tortoise, a ten-thousand-year tortoise, a hundred-year-old rabbit, no one will chase it " was a common saying that circulated in rural China. It means that even a turtle can stay alive for a long time and even a rabbit can run very fast in a short time. But who can catch up with whom after a hundred years? The philosophy behind this sentence was that time would change everything, be it people or things. Even if one thing looked very good now, its advantage would gradually weaken with the passage of time and eventually be surpassed by other things. And another thing, even if it seemed inconspicuous now, would gradually develop and grow over time to finally win. This sentence could also be used as a metaphor for people's lives. Sometimes, people might pursue some short-term benefits and ignore long-term planning and development, just like a thousand-year-old tortoise that couldn't maintain its advantage in the long run and was eventually surpassed by other things. Therefore, people should pay attention to long-term planning and development in order to achieve success with the passage of time.
