Xianghe is the first city in the world. It is located east of Beijing and three counties north of Langfang. It is located at the junction of Beijing, Tianjin and Hebei.

The overall approach of "shrinking the area without shrinking the scenery" was adopted to restore the old Beijing's "nine inside and seven outside" city wall layout. There are a total of 16 city gates and six corner towers. The towers and city walls were built in a 1:1 ratio according to the capital of Ming and Qing Dynasties, except that the length of the city wall was shortened (circumference 5 kilometers). The Dachang Nationalities Palace was designed by He Jingtang, an academician of the Chinese Academy of Engineering who is known as the "Father of the China Pavilion", and won a prestigious international award - the "American Architecture Award". The architectural design expresses traditional Chinese philosophical ideas in the form of "the sky is round and the earth is square". It is based on the traditional mosque. The building's appearance is square and stable, with the circular main body in the middle towering into the sky. The arches surrounding the building base form an elegant arc from bottom to top. There are 56 petal-shaped doorways in total, symbolizing the unity and prosperity of the 56 ethnic groups. Warm reminder: Xianghe meat pie is very famous, you can taste it after sightseeing.
