How to get to Wutai Mountain by car from Yungang Grottoes?

If you want to save money, take bus No.3 (1 yuan) from Yungang to the outer fork road to the terminal, and then take bus No.28 to Xinnan Station (1 yuan). After arriving at Xinnan Station, I stopped to buy a ticket to Yingxian County, not far from Wutai Mountain. Basically, there are buses that go directly to Wutai Mountain. Or it is more luxurious to take a taxi directly in Datong city.
