The Chinese Medical Doctor Association recently launched the 2014 China Sleep Quality Index research program in Beijing.

The program will investigate sleep quality of people from all walks of life in 40 cities across China, using online questionnaires and offline interviews, to determine the 10 most sleepless professions in the country.

Chinese data collection and research company Horizon Research Consultancy Group will carry out the research and analysis, sponsored by bed and pillow manufacturer Xilinmen, which will invite its customers to participate through a scannable code printed on its products.
