The story of Sun Ye riding a donkey (who should listen) was written in 300 words.

Once upon a time, an old man and a grandson went to the city for a fair. The weather is very hot. Grandpa rides a donkey, and his grandson leads the donkey. On the way, a passer-by saw them and said, "The old man only cares about his own enjoyment and lets the children walk on the ground." Grandpa also thought about it. He hurried down from the donkey's back, let his grandson ride on the donkey and led the donkey himself. Not far away, another passer-by said, "This child is really not sensible. He rode a donkey and let the old man run with him. " Hearing this, the little grandson was ashamed, and they decided to ride the donkey together. Not far away, an old lady saw the grandfather and grandson riding a donkey together and said, "These dads are so cruel. How can such a thin donkey resist two people riding?" Hearing this, Ye and Sun got off the donkey's back, stopped riding and simply took the donkey away. After walking a few steps, I met an old man and pointed to them and said, "This two fathers is so stupid that he is willing to walk without riding a donkey." Finally, the father and son decided to carry the donkey away. Not far away, passers-by laughed and said, "These two people are really thoughtful. It's okay not to ride a donkey. Why are they carrying it? "
