I  don't think so. first i from a china on 1967 year china was have a biggest  bag from a teacher. because the MAOZEDONG have give teacher a so low money,have give famer a lot money 
       on nowadays  teacher was more appreciated . 
       such as a math has 800 yuan for 3 hour,english has 1000 yuan for 3 hour .so the teacher were appreciated  and valued by society in the past than they were nowadays.
