What time does the flag raising ceremony in Beijing Tiananmen starts every morning and where to see Taichi?

The time of flag raising ceremony is a little bit different everyday. The concrete timetable could be found on this page: https://www.travelchinaguide.com/attraction/beijing/tiananmen/

Haven't seen morning exercise here. I think you could go to Jingshan Park or the Temple of Heaven, where the locals play taichi and other activities in the morning and afternoon.
