Today, Shenyang is developing with unprecedented spirit and ever-changing speed, surpassing any era in history. However, reality is a continuation of history, and today's achievements are based on history. If we want to build Shenyang well and make it develop better, faster, more harmonious, more distinctive and more culturally tasteful, we must understand its history. Therefore, history cannot be forgotten and should not be forgotten. What is history? History is the experience, experience and lessons of predecessors, as well as the inspiration and inheritance for future generations. When we look back on the history of Shenyang for thousands of years, we deeply realize that these long historical years, whether achievements or setbacks, whether joy or humiliation, are nourishing our spiritual wealth and inspiring us to create new glories.
