The Chengdu Metro uses a distance-based fare system, with ticket prices ranging from a starting price of 2 CNY to a maximum of 10 CNY for a single journey. Fares are calculated in increments based on the distance traveled: 2 CNY covers the first 4 kilometers, 3 CNY for 4 to 8 kilometers, 4 CNY for 8 to 12 kilometers, and subsequent increases until reaching the 10 CNY cap for trips over 50 kilometers. Travelers can purchase single-ride tickets using cash or mobile payment apps like Alipay and WeChat Pay at self-service machines in every station. For those planning extensive travel, a "Tianfu Pass" card can be purchased for a 20 CNY deposit, offering a 10% discount on fares, while unlimited-ride day passes are also available, priced at 20 CNY for one day, 50 CNY for three days, and 70 CNY for five days.
