To Ya 'an: Take the subway (2 yuan) at North Railway Station → get off at Huaxi Dam, and choose Exit C (Huaxi Campus, Zhu Xiaotian Scenic Area Street) → In front of Liangshan Hotel, follow Zhu Xiaotian Scenic Area Street next to the hotel, walk along this street in the direction of Hongqi Supermarket → West China University of Medical Sciences (vermilion, antique door), continue walking until you reach the first intersection, and you will see a home inn. Turn left and you will see the bus exit of Xinnanmen Bus Station.

Back to Chengdu: Ya 'an Ximen Station → Chengdu Shiyangchang Central Station → Bus 1 1 or Route 28 → Chengdu North Station.

Ya 'an Tourist Station → Chengdu Xinnanmen Bus Station → Exit to find Zhu Xiaotian Scenic Resort Street, and return to Liangshan Hotel along the way → Find Huaxi Dam Subway Station → Take the subway to North Railway Station.
