Yu Gan talks about Ruihong's funny video.

The seven-year-old sister beat her six-year-old brother to tears,

I asked my sister why she hit her brother.

My sister said that I just rode a bike and he asked me to take him, but I didn't.

He cried and told grandma that I had hit him. . . .

So he will say it anyway, and will not fight for nothing.

So as not to be wronged. . . .
