The right to health service is a basic human right，which requires the government to promote health service，and satisfy the health need of the citizens.After the establishment of the People’s Republic of China，an effective health service system，which dramatically enhanced the level of health service，was set up.However，there were problems，such as the heavy burden of the government and enterprises，vase gap of service between urban and rural area and the low quality of medical service，etc.Therefore，in the Reform and Opening-up period，the Chinese health service system has been reformed.Nonetheless，during this reform，there was a tendency of over-marketization，which was harmful to the protection of the right to health.From 2009 to 2011，the Chinese government put forward a new proposal of health care reform，concerning the health supply system，public health service，basic medicine system as well as public hospital reform，which makes a significant progress in the protection of the right to health.The only way to resolve the problems manifested in the reform shall be to deepen the reform.
