Plucking up a crop to help it grow
It is said that a short tempered man in the Song Dynasty (960-1279) was very anxious to hope his rice crop growing up quickly. He was thinking about this day and night. But the crop was growing much slower than he expected.
One day, he thought a solution to this. He plucked up all of his crop a few inches.
Even though he was very tired after doing this for a whole day, but he felt very happy since the crop did 'grow' higher.
His son heard about this and went to see the crop. Unfortunately the leaves of the crop began to wither.
This proverb is saying we have to let things go in its natural course. Being too anxious to help an event to develop often results in the contrary to our intent.
