Before the Spring Festival, cleaning up all the rooms is on the top of my must-do list. It doesn't sound like a big deal, but when I finally do it, everything is really different. The biggest problem is to decide what stuff should be kept or thrown away. In that case, I usually prepare four boxes to sort them out. I put the stuff which is really useless in the first box, and stick a tag on it saying "Throw away!" and I stick a “give away!” tag on the second box. Sometimes, I put in the second box the clothes and shoes I won't wear again, but which can be good for someone else. Then the third box will be filled with stuff which wasn’t in the right place so I can put them in the correct place later! So, I stick a "Put away!" tag on that box. Finally, I organize useful things and put them in the last box, then place it in a proper place that can be easily reached. This is my way of sorting stuff at home. If we want to keep our rooms always clean and neat, we should pay more attention to our desks. Desks are the main source of trash. We need to get into a habit of putting trash right away before leaving our desk.
