From Shaji River to the the Pearl River, from the river to the river, their footprints are left on the bank, which gathers volunteer service forces for water control. Recently, the "Green Beauty Guangzhou Volunteer Water Control Post Station" located on Shamian Island, Liwan District was officially unveiled. This post station is a voluntary water control service post jointly built by the Municipal River Mayor's Office, the Youth League Municipal Committee, and Liwan District on the basis of the original Shamian Volunteer Service Post Station, and is the first high-quality promotional position for the theme of voluntary water control in Guangzhou. It is understood that the municipal river mayor's office has updated the exterior decoration of the original Shamian volunteer service post station, adding the name of the water control post station with water elements as decoration, making the post station look more distinctive and dynamic. A variety of cultural and creative products are also placed in the post station. In addition, the billboards made by the river chief and the image posters of the Bobo river chief are placed on both sides of the post station, and the small program of "Building a Clear Water Dream Together" is combined to enable citizens to learn relevant knowledge and enhance the participation of the whole people in water management through online and offline connectivity. Ma Xueping, a representative of the folk river chief in Liwan District and the leader of the volunteer service team of the Shamian Volunteer Service Posthouse, introduced at the opening ceremony that after the post station is put into operation, it will actively spread the concept of loving water and protecting water to the public, gather the volunteer service forces of the whole people to participate in water control, strive to create a normalized water control station in the city, and better practice the water control idea of "opening the door to control water and everyone participating" in Guangzhou. Ma Xueping is a resident of Shamian, and she is very familiar with Shaji Chung. "In fact, it was carved by Britain and France after Shamian became a concession." Ma Xueping said that from the Republic of China to the early days of liberation, boatmen had been selling Congee on Shaji Chung - the now famous snack Yazi porridge. This shows from one side that the water quality of Shajiyong was good and edible at that time. In the 1990s, due to urban development, the water quality of Shaji Chung began to deteriorate. After that, the municipal government implemented a river sewage interception and remediation project, which effectively improved the water quality of Shaji Chung. The residents of Shamian have special feelings for this river that separates Shamian from 623 Road. Ma Xueping introduced that he regularly organizes voluntary activities to patrol the river and protect the river every month. "Before the activities, he will introduce the history of Shaji Chung to 'Hexiaoqing'." During the inspection process, the volunteers not only observe the color of the river, the environment on both banks, and whether there is garbage, but also record the pollution situation and communicate with relevant departments, so that the pollution problem can be solved in a timely manner. After the unveiling ceremony, under the leadership of representatives of the Liwan District River Chief Office and folk river chiefs, volunteers carried out river patrol and river protection activities. They walked along the the Pearl River and Shajichong and observed, comprehensively investigated whether there was sewage discharge and garbage dumping at the river bank facilities, river water quality, river outfall, and made records related to river patrol. After discovering the garbage on the embankment, volunteers skillfully used tools to pick up the garbage. It can be seen that before the upgrade of the "Shamian Volunteer Service Station", volunteers often disguised themselves as "environmentalists" to guard the river. The upgraded "Green Beauty Guangzhou Volunteer Water Control Posthouse" will also upgrade the content of the activity. Ma Xueping introduced that various forms of volunteer training on water control topics will be conducted online and offline, and interesting water control activities will be organized. Around the themes of "knowing water", "controlling water", and "enjoying water", interesting forms such as mobile stalls, drone river patrol experience, and Q&A interaction will be used to enhance the enthusiasm of citizens and volunteers to participate in water control, river patrol, and river protection, more
