History is the memory of a city, culture is the soul of a city, and the historical and cultural heritage of a city is the precious wealth left to us by our ancestors. General Secretary Xi Jinping emphasized the need to protect the historical and cultural heritage of cities like cherishing one's own life, and to develop and protect them while protecting them. Protecting the historical and cultural heritage of a city means protecting and promoting excellent traditional Chinese culture, continuing the historical context of the city, and safeguarding its vitality. Only by adhering to the principle of "protection first", strengthening "revitalization and utilization", and practicing "inheritance priority", can the historical and cultural heritage of cities shine with new vitality, new brilliance, and new value in the new era. Revitalize urban memory by safeguarding the historical and cultural heritage of the city. A city is a carrier of national culture and emotional memory, and historical culture is the key to the charm of a city. The formation of a city is the accumulation of history and the precipitation of culture. Our country has a long history and rich cultural heritage. Many cities have left behind a large number of cultural relics, historic cities, and cultural heritages during their hundreds or even thousands of years of development. They have preserved many ancient buildings, old houses, and old neighborhoods. These historical and cultural heritages carry splendid civilization, inherit historical culture, and maintain national spirit. They are precious legacies left to us by our ancestors. It can be said that the historical and cultural relics and their cultural heritage of a city are the root of its life and the soul of its memory. If the historical and cultural heritage is destroyed, no matter how new or good the city is built, it still lacks vitality. The ancients said, 'All things are born, but only know how to guard their roots.'. The Chinese civilization has continued to this day precisely because of this fundamental consciousness. However, in the process of rapid urban development in our country, some cities ignore the protection of historical and cultural heritage, destroy urban monuments and historical memories, and even engage in the reconstruction of ancient cities, demolishing real monuments and building fake antiques. They are enthusiastic about changing old and foreign place names, resulting in the "one face for a thousand cities" and "one appearance for ten thousand buildings". This not only cuts off the historical context, but also loses our national culture, causing cities to gradually "forget" and people in the city to become unfamiliar and distant. Cultural relics, without words, have their own spring and autumn; Historic sites are tangible, memories are immortal. Protecting the historical and cultural heritage of a city means cherishing, respecting, and revering ancient buildings, old houses, and old neighborhoods, emphasizing the inheritance of civilization, cultural continuity, and cultural context, and deeply understanding the philosophical wisdom of "where they come from and where they go" contained within them, in order to awaken and activate the historical memory of the city, and on the basis of respecting the laws of urban development, create a truly livable city. Empowering urban governance through the excavation of urban historical and cultural heritage. Just as any productive nation has a great national spirit, a charming city should also have its own unique urban spirit. The urban spirit embodies the heritage, taste, and wisdom of a city, and is what sets it apart from other cities. One important aspect of the formation of urban spirit comes from the historical and cultural heritage of the city. As important witnesses of urban development, these historical and cultural relics not only condense the city's past memories, but also shape people's cultural identity and social belonging, injecting indispensable confidence and motivation into its journey towards poetry and distant places. In this sense, the historical and cultural heritage of a city is a vibrant existence, consisting of frozen poetry, three-dimensional paintings, and down-to-earth notes. Each cultural heritage site has left behind stories of vicissitudes in the passage of time, and constantly unleashes new potential in the process of modernization. To protect the historical and cultural heritage of a city, it is necessary to deeply explore its spiritual connotation, activate and utilize its value implications in creative transformation and innovative development, so that it can radiate new vitality in the new era, and empower urban governance and economic and social development. To bring to life the cultural relics collected in museums, the heritage displayed on vast lands, and the words written in ancient books, we must deeply explore the ideological concepts, humanistic spirit, values, and moral norms contained in urban cultural heritage, so that it can fully play a role in providing public cultural services and meeting the spiritual and cultural needs of the people. Assist in urban renewal by inheriting the historical and cultural heritage of the city. The construction and development of a city is a systematic project that involves a wide range of aspects and has strong impact. It is necessary to coordinate the relationship between historical culture and real life, cultural heritage protection, and organic urban renewal. In other words, it is necessary to properly handle the relationship between tradition and modernity, inheritance and development. For the development of the city and even the whole society, the protection and inheritance of cultural heritage has given new vitality to Chinese culture, and has contributed an important force to promoting the Chinese path to modernization in which material civilization and spiritual civilization are coordinated and people and nature coexist harmoniously. However, in the process of urban renewal, the living space of historical and cultural heritage is inevitably squeezed. How to protect existing historical and cultural relics while ensuring the normal life of residents is a difficult problem faced by many cities in renewal. This requires us to plan comprehensively, adapt to local conditions, base ourselves on local characteristics, and find a balance between urban renewal and historical heritage inheritance, so that our city can better reflect regional characteristics, ethnic features, and contemporary style. That's why General Secretary Xi Jinping regards cultural inheritance as one of the basic principles for promoting urban development, emphasizing that "developing beautiful towns with historical memory, regional characteristics, and ethnic features cannot be a one size fits all approach." "Urban planning and construction should attach great importance to the protection of historical and cultural heritage, not rush for quick success, and avoid large-scale demolition and construction. We should highlight local characteristics, pay attention to improving the living environment, and use more micro renovation techniques such as' embroidery ', pay attention to the inheritance of civilization and cultural continuity, so that cities can leave memories and people can remember their hometowns. To protect the historical and cultural heritage of a city, it is necessary to find the connection point between traditional culture and modern life, continuously meet the growing needs of the people for a better life, combine cultural heritage inheritance with urban renewal, improve the living environment, and protect the historical and cultural heritage, so that historical and cultural heritage can be integrated into modern daily life and shine with new brilliance in modern urban construction. Only in this way can we inherit the charm of historical heritage, continue the long-standing cultural heritage, strengthen cultural confidence, promote high-quality urban development, and make people's lives better. The historical and cultural heritage of a city belongs not only to us, but also to future generations. On the new journey, we must adhere to the spirit of being responsible for history and the people, uphold the reverence for history and love for culture, and start from various aspects such as establishing coordination institutions for the protection and inheritance of cultural heritage, improving the system and mechanism for the protection and inheritance of cultural heritage, promoting systematic protection and unified supervision of cultural heritage, etc., to safeguard, utilize and inherit urban historical and cultural heritage well, and create new brilliance of Chinese culture in the continuation of urban historical context.
