It is the principle of "the unity of heaven and man" in China's geomantic omen that excludes the damage of human behavior to the natural environment, pays attention to human's induction to the natural environment, and guides people how to solve the site selection and even construction of buildings according to these induction, thus creating the east, west and south of China. The unique urban layout, architectural form and architectural landscape in North China and China are beautiful according to local conditions.
In contrast, with the opening up of the country, modern western architecture has blossomed everywhere in China, only pursuing concrete and single architectural grandeur, or single formal beauty, or functional practicality, or economic benefits, without considering the integration with regional, natural and historical conditions, resulting in the convergence of cities in China from south to north and from east to west today, which will be a sin that will leave a legacy forever.
