What are the funny lines of Changjiang No.7?

When my son saw the alien dog for the first time, he said, are you here to invade the earth?

The son shouted because he was afraid of suddenly seeing his father. When the father asked him his name, the son said, Dad, you look like a ghost!

Dad said in the last chat with an American female teacher: I recently found that my figure is a little different. I found that I am much more handsome!

My son dreamed that he had super powers and made trouble everywhere. The beauty teacher said it was time to turn around. My son said, the sea of suffering is boundless.
