Zhènxī
Zhenxi lies in the mountain country of old Lizhou, near the routes between the Sichuan Basin and the lands west of the Dadu River. At Qingxi, an old town in the Hanyuan district, a road crossed the Niba Mountains and brought caravans towards the town gates. The surrounding slopes were known for their Sichuan pepper, a fragrant local product valued far beyond the valley.
