Go to Yulin in Mid-Autumn Festival, seek accommodation and play routes.

I suggest you go to the incense burner temple in jia county on the 22nd. If time permits, you can go to Baiyunguan again and stay in Jiaxian at night. Hotels in Jiaxian are much cheaper than Yulin. On the morning of 23rd, I took a bus from Jiaxian to Yulin, first to Beitai and Hongshixia in Yulin Town, then took a bus to Hengshan County on the afternoon of 23rd, and lived in Hengshan County at night. The hotel fee is not much different from Jiaxian, so I went to Yulin Grottoes on the 24th, and then took a bus back to Xi from Hengshan County.

In addition, the scenic spots you want to visit are in Yulin City, Jiaxian County and Hengshan County, which are triangular. Whatever the arrangement, the schedule is quite tight. I suggest not going to Yulin Grottoes, but to Hongjiannao, which is also good, so your trip will only be in Yulin and jia county, and there will be plenty of time.

As for the standard room price, it's hard to say, because there is no decent hotel in Jiaxian, but one thing is certain, it's not expensive. You can check the standard room price in Yulin online, or call some hotels directly.
