What about sick leave pay maternity leave and pay?

A foreign teacher is allowed up to 30 sick leave days with the verification of a doctor. In some cases, if the illness is lengthy, the teacher receives a pro-rated salary for that time. The institution has the right to terminate employment if a teacher is not able to resume a normal working schedule after 30 days of sick leave. If a teacher is diagnosed with an illness that cannot be cured within a short period of time, arrangements are made to return that teacher to their home nation as soon as possible.

Institutions provide medical services to the teacher up to approximately 1,000 Yuan RMB ($120 USD) during a contracted period of time. In some cases, an institution will pay only 80% of medical expenses. Medical care is normally sought at the institution’s clinic or designated hospital. If a teacher wishes to go elsewhere, they must bear the medical costs themselves. There are no provisions for maternity pay.  The same medical information holds as for illness.
