Yiliang Jiuxiang Scenic Area

There is no rail to Jiuxiang directly, but to Yiliang. After that you would still need a bus etc to get there. Also, in fact it seems hard to connect the rail in Kunming since the time do not match. So maybe you can try to go from Chengdu to Kunming and then change to other bus instead. Online says there seems direct bus to Jiuxiang, if you annot find it, you can take bus from Kunming to Yilinag first and then another bus from Yiliang to Jiuxiang.
