getting to Hanging Temple from Datong

I've read that there is an almost direct bus from DT Bus station (located at No.3, Weidu Avenue) to Hanging Temple. I should get off in Hunyuan (is this the last stop?) and then to take a taxi to Hangin Temple, right?
The ride with the bus is aprox 1.5h? In some webs I've read 3h...Is Hunyan bus stop far from the Temple?
