In China, there are millions of middle aged urban women dancing together in public in the evening. They usually are aged between 40-60 and dance on plazas. After dinner between 19:00 and 21:00, these women come out of their home and gather at the open space of a plaza or of a park. With the music, they twist their waists and stretch our their hands like willows. The number of the group is usually about 20. But sometimes it can reach 200.
This evening after dinner I came to the plaza nearby. I watched them dancing for a while and then I decided to join. A woman played the role of a leader as she was in charge of the music and taught us a set of the act for a new song. When the dancing activity ended I felt really refreshed and uplifted. It IS a good exercise for women.
