More than 100 million Chinese are living with mental illness, but most of them are not receiving enough treatment. One rehab center in the Chinese capital is helping its patients deal with their problems in the kitchen, by giving them meaningful tasks and rewards. The center's program is called Crazy Bake and, as Rory Coen explains, it's proving to be quite effective.

Rolling the dough, and cutting it into shapes, you might be forgiven for thinking they're ordinary bakers, trying to get their orders ready for the morning rush. But these eight bakers are actually receiving therapy at a mental health facility in Beijing. They call themselves Crazy Bakers, and they prepare Cinnamon rolls, croissants and other types of bread three or four times a week. Ms. Yu has been a member of the team for six years, and she says she loves it.

MS. YU, PATIENT BEIJING CHAOYANG DISTRICT MENTAL HEALTH SERVICE CENTER "I used to just stay in the yard without doing anything. Every day was the same, nothing changed. But baking makes me use my hands and brain more often. It really helps."

The small bakery requires lots teamwork too. Some are responsible for grinding the cinnamon, others for buttering the rolls. These simple jobs were quite a challenge when Crazy Bake was founded 14 years ago. But now they're done almost without a thought.

DR. WANG KANGLE BEIJING CHAOYANG DISTRICT MENTAL HEALTH SERVICE CENTER "Baking has helped restore their labor capacity, social and language competence and enthusiasm to join social activities. The rehabilitation method is deemed very effective."

The bakers also get to see the outside world through deliveries and retail. Most of their customers are expats -- the locals don't seem to be as keen. At one international school, their bread sold like hot-cakes.

MR. TANG, PATIENT BEIJING CHAOYANG DISTRICT MENTAL HEALTH SERVICE CENTER "I like to come out and talk to people. It also encourages me to practice my English."

Their profits, although small, they get to keep. But you feel that they understand the real value of their hard work. Rory Coen, CGTN.
