20 10 during the Spring Festival, the park picnic area was closed due to air problems. In March of the same year, the picnic area of Tazishan Park was reopened. However, unlike in the past, barbecue will no longer be allowed in the picnic area, and instead, green picnics such as steaming and boiling will be used, and charcoal for picnics will also become an environmentally friendly fuel. After the charcoal burning in the picnic area is cancelled, the cost of tourists' picnicking will be greatly reduced, and 4 yuan with the lowest per capita can enjoy the fun of picnicking.

The picnic area of Tazishan Park carries a memory of Chengdu people: because it is the only outdoor picnic venue in Chengdu. The history of picnics in Tazishan Park began in the 1970s, when Tazishan was still a nursery and the park had not been built. The habit of having a picnic here in Chengdu began at that time, until the park was completed and the picnic park was standardized. By the end of 2002, hundreds of thousands of people invested in it, and the picnic park can accommodate more than 1000 tourists. Every weekend, the picnic garden is crowded with people. Citizens bring their own cooking utensils and vegetables and barbecue with their own hands. 120 stoves are often robbed, and those who come late have to queue up.
