In early autumn, walking into the historical and cultural block of Dongguan Street in Dalian, trams jingle, century old buildings stand quietly, and old brand shops, specialty restaurants, and trendy cultural and creative industries are cleverly integrated, creating a sense of "time travel" that interweaves historical culture and fashion experience. This century old street has been transformed and developed into a city card that combines historical memory and trendy temperament, attracting many tourists to visit and explore. Shenyang tourist Wang Xinyi specially came to Dongguan Street to check in and take photos. She said: "Here, we not only feel the historical and cultural heritage of Dalian, but also eat sea urchin dumplings, Seafood hot-pot, stews and other delicacies, and buy cultural and creative products with Dalian characteristics, such as refrigerator stickers, postcards, shell carvings, etc. It is really worthwhile." Dongguan Street is located in the core area of Dalian, with a total area of 8.13 hectares, 13 immovable cultural relics, 42 historical buildings and 132 traditional buildings, which is a vivid epitome of the local history of a century. This street is crowded with shops and bustling with people, offering a wide variety of goods. It is the birthplace of Dalian's ethnic industry and commerce, as well as one of the birthplaces of "time-honored brands". Previously, with the changes in urban construction, Dongguan Street, which had undergone a century of wind and rain baptism, once presented a dilapidated scene. The wires and clotheslines on the streets are disorderly, the residential courtyards are dilapidated, the sewage in public toilets is flowing, and the living environment is becoming increasingly worse, "said Yu Sainan, a guide at the Dongguan Street History Museum in Dalian. In the face of this situation, the local government has decided to promote the renovation and upgrading of Dongguan Street, taking the protection and utilization of Dongguan Street as a concrete practice to promote the revitalization of cultural heritage and implement urban renewal actions, and turning it into a new urban cultural and tourism landmark full of old style and artistic sense. In November 2022, the Dongguan Street Historical and Cultural Block Protection and Utilization Project was officially launched. The restoration of cultural relics in the neighborhood follows the principles of authenticity and integrity: detailed historical research is conducted on cultural relics and buildings, and their original appearance is restored based on original data, while retaining elements with historical value such as old brick walls and door frames; Coordinate the relationship between cultural relics and surrounding buildings, ensuring that the repaired buildings are in harmony with the neighborhood environment in terms of style, color, etc., and maintain the overall architectural style and spatial pattern. In September 2024, the renovated Dongguan Street Historical and Cultural District will be revitalized, introducing dozens of trendy shops such as "Backlight", "Unexpected Encounter", and "Cat's Sky City". Liu Ni, the person in charge of the "Plant Farm of Bran Rabbit" store, said, "After its opening, it has attracted a large number of young customers, and many old residents of Dongguan Street have come to revisit their childhood memories. We have specially made seals related to Dongguan Street, hoping to bring a unique imprint to everyone." Professor Hu Wenhui from the School of Architecture and Arts at Dalian University of Technology said, "Nowadays, Dongguan Street, which carries the memories of several generations, has been reborn as a 'living heritage', not only continuing the historical context, but also preserving the indispensable cultural soul of this modern city
