查询词典 function unit

Shang Dynasty was the initial period of urban development of China and the cities and countryside have not been split up, thus the primitive settlement shape has still been preserved, then these characteristics were formed: taking the palace area as the centre, the independent unit areas of comprehensive function surrounding and protecting the palace area. The city is an irregular concentric circle with the palace area as the center and expresses the thought of "the community".
