Xianglong 17.50 yuan, Erlang 16.00 yuan, Bird's Nest 14.00 yuan, Xiaojia 11.50 yuan, Longfeng (it seems there are no trains, you can get there by transferring 2 yuan at Bird's Nest).
If you want to recommend a trip to Longfeng Town, there is a tourist attraction there: Longduo Mountain and Baihe Reservoir.
My home is at the junction of Sanmiao Town and Longfeng Town. I wish you a pleasant journey!
