Dad, I want to go find Yan Zi. I must go!"

"Son? You are so fat! What can you do outside? You probably won't even have enough to eat!

Be good and raise cattle with dad. If you are gone, what will happen if our cattle fight again?"

"No matter! I just want to go to the United States. If I don't go? Yan Zi may not come back from the United States!"

...

A fat boy who was born and raised in the countryside...

In order to find his "childhood sweetheart" Yan Zi.

So he went to the United States alone.
