Foreign educators provide many services in China, but the poor incomes they are being offered are causing instability in the national education system, as Zhao Xinying reports.

Since China implemented the reform and opening-up policy in the late 1970s, the country's classrooms and lecture halls have become meccas for teachers from overseas, and it's estimated that at least 4,000 expat educators will be required nationwide in the next academic year.

However, despite the benefits brought by foreign teachers, the low salaries they are offered are causing disruption in the Chinese education system, according to industry insiders.
