Analysis of test questions: Qin died of tyranny, and "governing by doing nothing" learned a lesson in the early Han Dynasty, but from "governing by doing nothing" to "respecting Confucianism alone" has nothing to do with Qin, and A is excluded. The theme of the topic is to explain the change of the concept of governing the country. Item b discusses the changes in the local administrative system. Item b is irrelevant to the topic. Qin is a legalist thought. In the Han dynasty, Lao Tzu's learning came first, then Confucianism, which had nothing to do with Qin. C is wrong. Rulers have changed from "inaction" to "promising", and advocating the words of one family is the need and performance of strengthening centralization. The answer is D.
Comments: This question is difficult, which requires students to fully understand and master the mainstream thoughts of governing the country in Qin and Han dynasties, and to test students' ability of memorizing, analyzing and understanding.
