Chang'an City in the Tang Dynasty used to be a splendid Imperial Palace site, covering an area of considerable size. In Weiyang District of Xi'an, there are open areas and toll-collecting areas. It is suggested that the open areas should be better. There are many sites such as Taiyechi, Qilin Hall and so on. The best one is that the true Xuanwumen in the legend is on the northernmost side of the park to remember the flourishing Tang Dynasty as you like.
