Would you please recommend a boutique route for a four-day self-help tour in Shanxi? Detailed thanks

Going to Shanxi every year, I don't know whether to drive or fly/train. But Shanxi fights from south to north, so you can go in from Taiyuan and come out from Datong to avoid going back. If you drive by car, the later arrangements will be more complete but faster (the scenic spots are basically boutique routes).

D 1: Taiyuan and its vicinity: Lingshi Wangjia Courtyard (said to be the largest courtyard of Shanxi merchants) in the morning, Pingyao Ancient City and Jinci in the afternoon, and stay in Taiyuan at night;

D2: Taiyuan-Wutai Mountain. You can go to bigger and more famous temples such as Shuxiang Temple, Dailuoding Temple, Xiantong Temple and Zhenhai Temple to worship. Stay in Taihuai Town, Wutai Mountain at night.

D3: It's more fun to go to Wutai Mountain in the morning, to worship at Wu Ye Temple in the morning, and then to the Buddha Cave. Depart for Datong at noon, pass by Yingxian Wooden Pagoda and Hanging Temple, and stay in Datong.

D4: Go to Yungang Grottoes in Datong in the morning and return in the afternoon.

Time is tight. It's best to stay in Taiyuan for the first night. Because there were more scenic spots on the first day.

I think the tourist tickets in Shanxi are more expensive. It has risen sharply in the past two years. In the past, the tickets for the Hanging Temple and Yungang Grottoes were only about 30.40, but now they are all 130- 180. There seems to be a discount on the military certificate, which is not clear.
