It’s great to hear from you. I feel proud knowing your interest in Chinese literature. The set phrase you asked me means Trying to help seedlings grow by pulling them up. There is a story behind it.
A man in the Song State was anxious about the slow growth of his seedlings. One day, he went to the field and pulled them upward one by one. He came back tired and said to his family, “I’m exhausted today, for I have helped the seedlings grow much taller all at once.” Hearing this, his son ran to look at the seedlings. To his horror, all of them had dried up and died.
This set phrase means that growing against the law of development in things and being overanxious for quick results will make things worse.
Looking forward to hearing from you.
