Ruan Qing wrote in Beijing Daily that in the process of studying and practicing Scientific Outlook on Development, all localities are speeding up their pace, actively promoting socialist modernization and putting forward many distinctive slogans. Among them, "great changes in three years" or "great changes in x years" may be one of the slogans to put forward more regions. It should be affirmed that the slogan of "great change" reflects the courage of some leading cadres who want to do things, want to do things, and dare to do things. But if we carefully understand and ponder this slogan, we always feel that it has the color of "Great Leap Forward". Moreover, in some places, in order to turn slogans such as "three years of great change" into reality, the great change is limited to the great change of urban architecture. Therefore, it is necessary for us to seriously study the scientificity and rationality of slogans such as "Three-year Great Change". First of all, what has changed greatly? Undoubtedly, the so-called great changes should mean that with the deepening of socialist modernization, the overall outlook of people's lives has undergone fundamental changes. If the big changes are limited to the big changes of urban buildings, then many new problems will inevitably arise due to the lagging development of other aspects. Secondly, is it possible to achieve great changes in a short time, such as three years? The development of everything depends on certain conditions and has certain regularity, which is manifested as a process. The formation and development of a city is a long-term historical process, which is first manifested as a cultural accumulation. Therefore, any city with good development prospects can not be achieved in a short period of time. In addition, we must be soberly aware that in the process of economic and social development, some things will change greatly, and some things will never change. First, the green mountains and green waters must not change, which is the natural basis for human survival. Second, the excellent historical and cultural heritage must not be changed, which is the spiritual foundation on which our nation lives. Third, the party's purpose of serving the people wholeheartedly cannot be changed, which is the foundation of our party building and governance. Therefore, in the process of economic and social development, we must proceed from our own reality and carefully study and determine which ones will change greatly and which ones will not; What should be changed must be completely changed as soon as possible, and what should not be changed must never be changed under any excuse; Actively explore how to choose and cultivate our urban culture, how to show our culture in the process of urban planning, and how to embody our culture in every detail of urban construction. We must never simplify, vulgarize or slogan "Great Change".
