When Peiping was just liberated, the southern area of Dongcheng, especially outside Chongwenmen, due to low-lying terrain and backward municipal facilities, coupled with the longsu ditch in the south and the stinky ditch of Dashiqiao in the north, the reed pond was continuous, mosquitoes and flies were born, and the environmental health was extremely poor, which seriously affected the people's life and health. The municipal party committee and the municipal government attach great importance to this, and at the beginning of liberation, they set up a cleaning campaign committee composed of the party, government, military, industry, agriculture, academia, and business circles to organize the masses from all walks of life to vigorously carry out environmental improvement and sanitation and epidemic prevention work.
The old appearance of Longsugou before liberation
The 8-kilometer-long Longsu Ditch is an open ditch that has lasted for more than 150 years, where all the rainwater and sewage from less than 350 hectares in the southern part of the city are collected, and it has become a stinky ditch because it has not been dredged for many years. Due to the stinking sky, mosquitoes and flies, and every time there is heavy rain, the ditch will overflow, it is the birthplace of epidemics and infectious diseases in Nancheng, bringing serious harm and disaster to the residents of Nancheng. In order to eradicate this stinky ditch, in February 1950, the Municipal Sanitation Engineering Bureau established the Longsugou Engineering Office, and from May 16 to July 31, the first phase of special rectification of Longsugou was carried out, and four sewer main pipes totaling 6070 meters were buried in goldfish ponds and Tiantan roots; the second phase of the project was carried out from October 12 to November 22, burying 2433 meters of sewer main pipes in the section from Hongqiao to southeast moat, and changing the open ditch into a dark ditch to fill in the Longsu ditch. Since then, the relevant district party committees and district offices have organized the repair of roads, the installation of electric lights, the installation of running water or the construction of public water stations, which has brought about earth-shaking changes in the environmental health situation around Longsugou. In that year, the writer Lao She used this as a material to create the drama "Longsugou" (premiered by the Beijing People's Art Theater in February 1951 and later adapted into a movie), which vividly praised the people's government for wholeheartedly doing practical things for the people, and had a great impact on the whole country.
From 1950 to 1951, longsu ditch was rectified, and the open ditch was changed to a dark ditch to lay a sewer pipeline.
According to historical records, the goldfish pond was the place where goldfish were raised in the Gold, Yuan, Ming and Qing Dynasties. During the Republic of China, the goldfish pond became increasingly deserted, and by the time of the liberation of Peiping, only a pool of turbid water remained, which became a breeding ground for mosquitoes and flies.
From September to December 1951, the municipal party committee, the municipal government and the relevant district party committees and district governments organized manpower and material resources to carry out the first transformation of the area, renovating the irregular goldfish pond into a "concave" shaped Yuanbao Lake, with cement railings on the shore of the pond and weeping willows planted along the shore, which became a small park for people to relax.
From 1950 to 1951, the renovated goldfish pond was dug up and built into a small park.
In 1965, a second renovation was carried out, filling in the dried up goldfish pond and building 69 simple residential buildings for the public to live in. After more than 30 years of use, especially after the Tangshan earthquake, the walls of most buildings have been deformed, some have serious rain leakage, coupled with the lack of heating, gas and other facilities, the life of residents is very inconvenient.
In the 1960s, new residential buildings were built after the goldfish pond was filled in.
In 2001, the former Chongwen District Party Committee and the District Government decided to take advantage of the municipal government's preferential policies for the crisis reform of nancheng to overcome difficulties and carry out the third large-scale transformation of the Jinyuchi area. The Goldfish Pond Renovation was the largest simple building renovation project in the city at that time, covering an area of 10.27 hectares, with 58 dangerous old buildings, 492 bungalows and 41 municipal and district units. On July 28 of that year, after careful planning and preparation, the construction of the Goldfish Pond Dangerous Transformation Zone officially began. After 10 months of intense construction, the Jinyuchi Community with beautiful environment, complete facilities and outstanding scientific and technological and cultural characteristics was completed, and the per capita housing area of residents reached 27.6 square meters, exceeding the housing standard of 18 square meters per capita proposed by the municipal government at that time.
In 2002, after three large-scale renovations, the old appearance of the Goldfish Pond Community was renewed.
