Jinsha Ecological Park, where I barbecue every year, is a basketball court and a football field, with badminton courts, seesaws and swings (just tell taxi drivers about Jinsha Ecological Park in Shuikou Village) or take the bus terminal line (12 stop) at the gate of the railway station to Jinsha Ecological Park (Shuikou Village).
The fare to 2 yuan is about 3 yuan per person, which will be more expensive on holidays. You can rent basketball and football to play. I hope I can help you.
