I have been listening to others say that the Hemuling Great Wall is well preserved. I went to play with my classmates. I booked lunch at this farmhouse before climbing the Great Wall. It was already more than 2 o'clock after climbing the Great Wall. I called the proprietress before going down the mountain. When I waited for the restaurant, the dishes were all up. The efficiency was very high and the dishes were very good. Not worse than the big hotel! And the environment inside is very good, there is a feeling of cave, highly recommended!
