Zhengding ancient city, it may be the first time I heard of it, and I will be impressed if I have been there
Together with Beijing and Baoding, it was once known as the "Three Heroes in the North". City walls of this scale are rare in the whole country.
Under the setting sun and in the night, each has its own beauty, and the ancient buildings located all around make this place full of historical atmosphere.
Liang Sicheng once lamented that "I have never witnessed so many historical sites in such a small place and in such a short time".
