拔苗助长 (bá miáo zhù zhǎng)
Long, long ago, a farmer thought the shoots in his fields were not growing fast enough. He wanted to help them. So he pulled every shoot up, then went home, feeling very tired but very satisfied. “Look, how great I am! I can think out such a good idea. From now on, my shoots will grow faster and faster,” he thought. “I am very tired today,” he said to his family, “I’ve been helping the young shoots to grow.” When his son heard this, he ran out to the fields to have a look. To his surprise, he found all the shoots were dead.
