As China’s development is becoming increasingly rapid， more and more Chinese people choose to go abroad to see the world and also more and more foreign people choose to live and work in China. Both the supply and demand are prosperous， so the field of "foreign teacher” has roared. However， since the case that a British escaped criminal who conducted sexual abuse of children and “concealed” himself in China as a foreign teacher was exposed in 2013， “foreign teacher” as a profession has gathered the attention and questioning. Some industry insiders said the chaotic phenomena have existed in the market of foreign teachers for a very long time.
　　随着中国发展的步伐不断加快，越来越多的中国人走出国门看世界，也有越来越多的外国人选择到中国生活和工作。供需两旺，“外教”行业迅猛发展。然而，自从2013年英国一名性侵儿童的逃犯在北京“潜伏”了三年并当了外教一事被曝光后，就引发人们对外教市场以及“外教”这一特殊职业的种种关注与质疑。一些业内人士称，外教市场的乱象存在已久。
