What is Zhang Qinnan's reading method for cities?

Zhang Qinnan said that he was engaged in architecture and gradually developed the habit of studying in the city. Everywhere he goes, he always looks for a map to understand its layout. Then he visits its signs, observes its buildings, streets, trees and people's daily necessities, and tries to feel its cultural characteristics. Over time, a set of reading methods has gradually formed. This method is not creative, and it is basically "brought". The first one was taken from the "cognitive map" advocated by KevinLynch, an American urbanist and professor at MIT. The method is to let a non-professional draw a map of the city according to his own impressions and memories. Generally speaking, he always remembers only a few landmark buildings (Eiffel Tower, Arc de Triomphe, Bastille Monument, etc. ) and main roads. However, this "cognitive map" hidden in everyone's mind has become a reference coordinate map for him, and he can find the direction without the guidance of a map. In fact, this often becomes the first achievement of studying in the city.
