Want to go to the Yungang Grottoes in Datong, the ancient city of Pingyao, how to arrange the route of Hukou Waterfall?

I don’t know where you start from, and where you return from in the end. You can only arrange it from north to south. The route is Yungang Grottoes~Pingyao Ancient City~Hukou Waterfall. <br/>D1 Yungang Grottoes in the morning, there is a direct bus from the railway station to Yungang, Yungang tour takes about 4 hours, return to Datong City in the afternoon, visit Huayan Temple and Nine Dragon Wall, have dinner at Fenglin Pavilion, and then sit Train No. 2463 to Pingyao Ancient City. <br/>D2 Pingyao Ancient City, stay in Pingyao. <br/>D3 Take the train from Pingyao to Linfen. After arriving in Linfen, you can sign up for a one-day tour in Hukou.
