There are many poems about the frontier in the Tang Dynasty. When the Tang Dynasty was strong, many literati had the opportunity to experience the border, so many famous poems about it were written, especially about Yumenguan. For example, the very famous phrase "Spring Breeze is not good" . The site of Yumenguan is now a small square in the northwest of Dunhuang, Gansu Province. Today, it is just a ruin. The core area is centered on the site of Xiaofangpancheng. Yumenguan is not the same as it used to be. If you really want to come here to see the Great Wall, you may be disappointed. It is very desolate here, a piece of ancient city wall ruins and a stone with a red letter of Yumenguan, even the entire attraction.
