Haste makes waste
揠苗助长 (yà miáo zhù zhǎng)
This is an HSK chengyu
《孟子》(Mèng Zǐ), a classic Confucian work written by the philosopher of the same name. The work is often known in English as "The Book of Mencius."
A long time ago, there was a farmer who was worried that his rice crops were growing too slowly. He made a point of checking on them every morning, but it never seemed like they'd gotten any taller. When he realized that his neighbors' crops were starting to grow taller than his, he began to truly despair, and he vowed to find a way to move things along more quickly.
One morning, he was struck with a fantastic idea. He rushed down to the fields and started tugging all of the new growth so that their roots sat a little higher in the soil. He worked hard for the entire day, and when night finally started to fall, he returned home and proudly told his family about how he'd helped the sprouts grow.
Immediately, his son looked up in horror. A moment later, he leapt to his feet and hurried out to see the fields. Sure enough, all of the sprouts had withered and died, and the entire crop was lost.
