Guangzhou is still cool in April. On the day we went to Shijing River for an interview, it was raining in Mao Mao, and the turbid wind had a strange smell. The reporter bent down to vomit, but the card friends who played cards by the river didn't care. The shouts of "Red Heart K" and "Box 5" are endless.
The river was dark. From the reflection of water, you can see floating dead leaves, magnificent buildings, and more rows of low-rise bungalows. The river is calm most of the time, but occasionally a cleaning boat comes. "It's much better than before, but it's still a lot of rubbish," said a cleaner on board. "Some float upstream, and some blow down from both sides."
According to the preliminary design scheme of Baiyun District, the problem of "black odor" of Shijing River was completely solved by measures such as sewage interception, dredging, water replenishment, embankment construction, rain and sewage diversion and landscape construction.

First of all, the comprehensive renovation and demolition work of Shijing River is divided into four streets: Tongde, Songzhou, Hejun and Shijing, and the "Responsibility Letter" was signed, making it clear that all land acquisition and demolition work will be completed before June 30, 2009. At the same time, start the rain and sewage diversion project of the main road in Shijing River Basin. In addition, the preliminary design and budget preparation of the comprehensive improvement project of Shijing River are being carried out in Baiyun District. Through the measures of sewage interception, river bed dredging, rain and sewage diversion on both sides, combined with Baiyun Lake water supply project, the water environment of Shijing River was improved.
