★★★★★ I went to the riverside park to exercise at 6 o'clock this afternoon. I don’t know what organization was taking up the entire playground. They kept escorting us away, completely occupying the entire playground to engage in their movements. They asked us to leave in a very rude language, and the attitude was very tough. However, when we came in, we did not see any announcement telling us that the playground was closed today. I really want to complain about them. But I don't know what organization they are and who is responsible. I only know that they were already there at 6 o'clock in the afternoon of 2019-06-12. I feel very angry. Other friends also feel unhappy.
