    One day， a mother horse told her son， "My child， will you happily go and carry this bag of wheat to the mill （磨坊） to grind it into flour？" The little horse happily agreed without hesitation， and ran out of the house with a bag of wheat on his back．
    After quite a long journey， the little horse came to a river， which blocked his path to the mill． He suddenly got confused． Looking around， he saw a cow． So he asked the cow， "Auntie Cow， can you tell me whether I can cross the river？" The cow answered， "Definitely you can． The water is very shallow．" When the little horse was about to cross the river， a squirrel shouted to him， "Little horse， don't cross the river． You will drown．" The little horse didn't know what to do， so he decided to go back to ask his mother．
    After he told his mother everything that happened on his way， his mother said， "My child， it's not enough to only listen to others； you have to give it a try by yourself， and then you'll know the answer．"
    With those words， he walked carefully across the river． The water was neither shallow nor deep． It was just fine for him． Finally the little horse crossed the river and completed his task．
