The historical development of seventy-two selling houses

"Seventy-two Selling" is famous from T-selling and Xigu in the northwest, followed by Zhigu in the northeast, Gu Ni in the east and west, and Dagu where Haihe River enters the sea. Xigu and T-shirts are sold closer. Zhu Daojiang, a poet in the early Qing Dynasty, said in a poem: "Luwei is connected with the sea level, and Dinggu has long been famous for its scenery." Now the Luhe River is the North Canal and the Weihe River is the South Canal. Two rivers flow into Tianjin and meet in Bali in the north of the city to form a T-shaped valley, hence the name T-shaped Valley. Xigu once set up Guandu in the Ming Dynasty, and Kangxi in the Qing Dynasty set up a pontoon bridge at the former site. After the Republic of China, peach trees were planted all over the north river bank, which bloomed in spring and became a spring resort in Tianjin. On the eve of the Anti-Japanese War, there were not many peach trees left, but the reputation of Xigu Taolin was still there. The former site of the Naval Academy and the armory in the late Qing Dynasty later became the school building of the famous Beiyang University, located on the side of Tao Di in Xigu. Zhi gu is the floorboard of Sanchakou residential area in Tianjin since Ming and Qing Dynasties. Specific location, "Yu Fang Minutes" said that it was ten miles southeast of the county, and the branch valley was affected by the mass flow, and the branch valley was in the southeast, and the mass flow was endless, so it was called the branch valley. The place name of zhi gu, which has been handed down, is on the east bank of Haihe River today. There are many woks in the local area, which are famous for brewing sorghum white dry wine. The wine produced in Tianjin is known as "Zhigu wine" all over the country. Salt water is sold in the southwest bank of the middle and lower reaches of Haihe River, as well as Gegu, Taoyuan Valley and Sini Valley. At that time, I set out from the city pier of Haihe River by steamboat and visited these places along the river. Xianshuigu and Gegu are two big towns in the suburbs of Tianjin, four or five miles southeast of the urban area. It is said that the sea river is at high tide and the salt water stops here, so it is called selling salt water. Where the Haihe River enters the sea, Dagu confronts Tanggu. The nine famous saline-alkali chemical plants in modern times and Li Yong saltworks are located in Dagu Lake. The salt fields on the beach are dazzling and endless; Pumping windmills soar into the sky, compared with soaring seagulls. There is a big shipyard on the other side of Tanggu; There is a modern harbor here, and huge ships are moored in the harbor, which is very spectacular. Tanggu residents are good at shipbuilding and fishing; Tanggu also means hometown of overseas Chinese. In the early 1980s, Tianjin set up an economic and technological development zone in Tanggu to open to the outside world, and the construction of Tanggu and its port advanced by leaps and bounds!
