Hundred Birds Park is also good. On Chongshan Road, there is a Huanggu Gymnasium next to it, which seems to be charged.
Opposite the Hundred Birds Park is Liaoning University, with a basketball court and playground (nonsense. Hehe). It can be reached at both the East Gate and the West Gate during the day. I've been in and out countless times.
Far to the east is Beiling Park, where many people do morning exercises, evening exercises, spring, summer, autumn and winter. It's convenient to take the bus because it's too far.
