Community buses in Chengdu are generally free of charge by swiping their cards with bus cards. Whether you use a prepaid bus card or an e-wallet, you can ride for free. If you don't have a bus card, you need to pay for a ticket. Please note that community buses may impose restrictions on the number or time of swiping cards, such as swiping cards twice to ride for free, or swiping cards for a certain period of time to ride for free.
For specific free policies and restrictions, please consult the local bus company or check the bus company official website for details.
