The city is the patient the planner faces. Different from physics and chemistry, medicine and urban planning are both empirical disciplines. The accumulation of “medical records” is an important means of academic progress. A good doctor does not accurately repeat the symptoms, but predicts the progression of the symptoms through the symptoms and puts forward the prevention and cure. The same is true of urban planning. The “good” plan should be able to “cure the disease” - predict “lung cancer” before “smoking.” Obviously, at present level of discipline development, the ability to “cure disease” can only come from the induction of a large number of cases. In 2002, the famous city of China Urban Planning and Design Institute gave Beijing city
