Is the bus from Chongqing to Fenghuang still available at Longtousi Bus Station?

Yes, you need to take a direct long-distance bus from Longtousi South Bus Station (located at South Square of North Railway Station). As I know, the bus schedules is 12:30. The ticket fare is CNY 165 per person. In addition, the official booking page doesn't have English version. You need to arrive at the coach station early and purchase the tickets there. :)
