Campaigners are calling for better treatment of the 30 million people in China who have been diagnosed as clinically depressed. Wang Xiaodong reports.

Mo Qing (not his real name), a 30-year-old university teacher in Zunyi, Guizhou province in southwest China, was diagnosed as being clinically depressed 10 years ago, but his life has frequently been subject to bouts of despondency and dejection.

His condition began to stabilize about a year ago, but he occasionally still experiences temporary outbreaks. "Things are getting much better than before," he said. "Nowadays I can sense every impending outbreak from the symptoms, so I adjust my medication accordingly to handle it."
