We Chinese people thought moving could let everything start over, and kick the bad things off.
When we moving, we throw something old out and buy something new back in. And we are gonna know some new friends, new places when we get the new home. But moving is a hard work also. So we need our friends help us to do it. Everybody gets together, have something eat and drink, talk about someting interesting. It is fun, like the 1st floor said.
