In the Oscar-winning movie Silver Linings Playbook, Pat, a monomaniac who refuses to face the breakup with his ex-wife, and Tiffany, a widow whose life is a mess after her husband's death, heal their wounds by preparing for a dancing competition together.

They forget their troubles when they focus on practicing the jumps and lifts. They build up trust and love for each other with silent touches rather than flashy words.

Dancing turns out to be a miracle drug for the two mentally ill people.

And it also has become a trendy antidote to stress among young Chinese, especially urban female white-collar workers, in the past three years.

After a day of exhausting work, they go to "dance therapy" studios, which are usually in or near their cities' central business districts and thus not far from their offices; take off their high heels; and put on sportswear to learn about their own bodies so as to release the emotions locked in the shells.

Wang Yuchi is the first dance therapist in Guangzhou, capital of Guangdong province, and has been offering the service at the Sun Flower Counseling Center since 2010.

She has given dance therapy courses to about 50 people, each 10-week course carried out among a group of only five or six people.

A weekly class begins with participants relaxing their bodies by doing whatever movements they want to do. They are asked to put aside rational thinking and to just follow what they feel.

Then Wang will guide participants to observe and imitate each other's movements and share what they guess their teammates are feeling. "Remarks from others can help a self-restrained person to crack open the body to feel the emotions inside," Wang said.

Only when trust is built within a group will Wang start individual case studies. During a case study, the therapist designs movements for a particular participant to follow based on previous in-depth personal interviews in order to put the person in a situation similar to the one where he or she got the emotional scar.

The other members in the group surround their teammate to offer a sense of security, holding the person's hand when he or she gets too emotional and thus shakes and tumbles. They also listen to the person baring the old wound.
