In Beijing, there are a few parks where there are more people doing ballroom dancing in the mornings, including South Lake Park and a certain cultural park in Tongzhou, among others. In South Lake Park, ballroom dancing is more frequent in the mornings, especially on weekday mornings, when more people may need to take care of their children or have other arrangements. In a cultural park in Tongzhou, a large number of cotillion enthusiasts also gather there for activities. All these parks provide good environment and facilities for people to enjoy nature and beauty while dancing.
Of course, in addition to the parks mentioned above, some other parks may also have crowds of ballroom dancers, depending on individual preferences and specific locations. If you're interested in a specific park, check with your local community organization or park authority for more accurate information.
