I'm receiving lots of letters every month in my daily life, such as all kinds of bills, notices and so on. When i looking at those envelopes, this seems to me a waste. One day i decided to make them into notebooks, and now, i'm using those notebooks i made everyday in class. BTW, the quality of envelope paper is really not bad.
我现在的日常生活里，每月都会收到许多信件，像各种缴费单、通知单、医院检查报告等。看着这一沓沓白花花的信封，真心觉得实在浪费纸张，想着现在上课反正都要买笔记本，倒不如把这些信封装订成笔记本，既节省成本又环保实用，关键是纸质还不赖!
