The young and the aged must respect each other

Not wrong to charge people for using public facilities

In Shanghai, for example, some social organizations are providing such public services, in order to ensure that square dancing does not affect normal community life.

If some groups or individuals continue violating the rules, regulators should impose higher fines on them until they fall in line. Also, it's not wrong to make residents pay for using playgrounds and parks, especially if such sites attract conflicting parties that could lead to arguments, even violence, to maintain public order.
