Located on the very corner of Lao Chengdu Bei Lu and Dagu Lu and technically called the "Yan'an Zhong Lu Large Public Green Space," this is one of the nicest downtown parks. Lots of cherry trees, waterfalls, and opportunities for scenic selfies. The southern edge also houses the Site of the Second National Congress. As with most parks, tons of elderly folks playing board games too. Free all day. Open 24-7.
