A system to provide better treatment for people who suffer mental health problems is being established by the Ministry of Health.

The cornerstone of the system is an information network to replace and upgrade figures that are almost certainly obsolete. So far it has helped nearly 3 million patients.

"The system is still being set up and we are working hard to improve it," Yan Jun, who heads the mental health division at the ministry's Disease Prevention and Control Bureau, told China Daily in an exclusive interview.
