I gave up the reservation directly inside the temple. I didn't want to waste time on it. We will meet each other if we are destined to. The 15 yuan ticket is still worth going in to take a look, take pictures, and see the places where the ancients have been. It can be regarded as a trip to Hengshan. However, it does not have the same entrance as Hengshan. The 20 yuan bus ticket is universal. If you drive yourself, it is more convenient to leave it at the visitor center and take the universal bus. Our car was left at the Hengshan entrance, which was not very convenient. There are quite a lot of universal buses. Anyway, the ticket is 20 yuan for several trips a day, and we basically did not queue.
