Well, you can take a taxi to North Bus Station first. It costs CNY30-40. There are several coaches that can take you to DJY Bus Station. The bus schedules are 07:50, 08:40, 09:30, 10:30, 11:20, 12:10, 13:00, 13:50, 14:40, 15:20, 16:10 and 17:00. It costs CNY 14 per person. After arriving, take a taxi to the scenic area directly.
