And we will be the future leaders of China. Some day we have to work hand in hand with each other and make China more and more beautiful. So we must learn to love each other like brothers and sisters.

It’s hard to think how difficult life would be if we had a sibling(同胞，手足).We never have to share anything at home. Of course, we might have cousins, but we don’t have to live with them!
