One day, the donkey and the white horse went to the mountains together.

On Pingchuan Avenue, the white horse raised its hooves, raised its tail, and soon left the donkey behind. The white horse turned around and looked at the donkey. He saw it wagging its two big ears and walking slowly. It was very anxious, so it yelled at the donkey: "Hey, why don't you step a little tighter? Look?" You look so slow, when will we get to our destination? You black donkey, you are such a mediocre person!"

The donkey was neither angry nor discouraged after hearing the white horse's scolding. Walking forward step by step.

After the donkey and the white horse entered the mountainous area, the mountain road became steep, narrow, and rugged. The white horse's speed slowed down unconsciously, and the sweat on his body seemed like he had just taken a shower. But the donkey quickened its pace and rushed to the front.

The white horse saw how easily the donkey walked along the narrow path, and asked puzzledly: "Black donkey, why are you walking faster than me on the mountain road?"

Donkey He replied: "Because there are specialties in skills, each has its own use. Those who lag behind under certain conditions are not all mediocre!"

After hearing what the donkey said, the white horse looked at the donkey's calm look, I feel very ashamed of what I just said.

Comments on the fable:

"A ruler is short, an inch is long." No one is perfect, but no one is useless. The white horse is much faster than the donkey on Pingchuan Avenue, but it is not as fast as the donkey on the narrow path. This is due to changes in the environment, and the performance of individual skills also changes.
