When we were young ,our pocket money maybe RMB 5mao,5yuan .And 50yuan ,100yuan is a high price of money itself.Especially the 100yuan could do a lot things ,like exchange goods ,pay a bill . When we were children ,100yuan is so worthy that help us get wishes come true and bring fun ,happiness .But in the year 2011,after we leave a supermarket with hands taking plastic but little things in it .We may say goodbye to 100,200yuan or more . What's the matter with you ,100yuan .
