From December 2020, a project named "Ancient City Cell Anatomy Project" will be launched in Gusu District, Suzhou City, Jiangsu Province. Every "cell" of 54 neighborhoods, houses, ancient wells, ancient trees and bridges within 14.2 square kilometers of the ancient city of Suzhou will receive a comprehensive and in-depth "physical examination" in this project. "There is no end to the stories of the old city streets. Every old resident is a living treasure, and every historic site has a vivid past. The excavation of characters, customs and important space elements is the inheritance and collection of Suzhou's history and culture." Wang Yongfa, director of the Planning and Protection Division of Suzhou National Historic and Cultural City Reserve and Gusu District Ancient City Protection Committee, said. Anatomical census, each nameless courtyard has an "ID card" Anatomical census gives a clear picture of the past life, present life and pattern evolution of the old house, which is equivalent to an "ID card" for each original nameless historic site. These material and cultural information will provide scientific basis for the overall protection and renewal of the ancient city. In the summer of 2021, a group of "ancient city cell anatomists" wearing sunshade hats and holding cameras, recording pens, measuring tapes and other equipment will shuttle through the streets and alleys, door-to-door, collect aboriginal reputation data in a routine way, and collect historical elements such as gatehouses, boundary stones, inscriptions, and ancient wells, making the collection results more three-dimensional and full. Gusu implemented the "Ancient City Cell Anatomy Project" in different regions. The first four neighborhoods, No. 20, No. 32, No. 15 and No. 7, were selected for general survey with the standard of no less than 95% of the households. "We regard the traditional residential buildings and structures in the ancient city as the 'basic cells' of the ancient city structure, and entrust professional institutions to comprehensively collect residential building information and historical evolution data to form a building directory and basic data." Qi Yating, a staff member of the Rules Protection Division of Gusu District Ancient City Protection Committee, said. In March 2021, the general survey team of the "Ancient City Cell Anatomy Project" came to Block 32. According to an 80 year old aunt, in the early years, there was an old house in front of their house, which everyone called the Mandarin Duck Auditorium. According to this clue, Zhang Yushu, the technical director of the project of Suzhou Planning and Design Institute Co., Ltd., found by looking up historical data that the building was the residence of a gentry surnamed Wu in the late Qing Dynasty. New style weddings began to be popular in the Republic of China period. Most enlightened gentry and educators in the old city advocate "Western weddings". The Yuanyang Auditorium in Neighborhood 32 was the place where new style weddings were held at that time. This discovery shows that the traditional folk custom of "marriage" in Suzhou during the Republic of China was changed under the influence of foreign cultures. Also in the No. 32 Neighborhood, the team found the site of the current Suzhou Instrument Components Factory, where there was a celebrity residence in the late Qing Dynasty. There is a famous small garden pot garden in the northwest corner of the house. Whether looking from south to north or from north to south, the garden is a landscape composition with deep bamboo trees. Mr. Liu Dunzhen said that the pot garden is "a good example of a garden with a pool as its main scene". "With the acceleration of urbanization, the disappearance of material heritage is inevitable, but its history and culture are still there. We also pay great attention to the excavation of these old houses that have been lost, because they are also an unforgettable memory of a city." Zhang
