　　A few days ago, there was a short video on the Internet, which captured the picture of water accumulated during the rainstorm in Cining Palace of the Palace Museum, questioning the function of the drainage system of the Palace Museum. It is also said that there is no water in the Forbidden City for 600 years, and the serious water accumulation in the Forbidden City is caused by modern technology. Is it true?

　　The reporter interviewed the staff of the Forbidden City and said that the Ming and Qing Dynasties would open the culvert for dredging every March. At present, the Forbidden City carries out dredging three times a year in spring, summer and autumn, and there are quite a few dredging times. Why is there still water in Cining Palace? It's not that modern science and technology can't clear the mud, but that the staff found products only available in modern society in the culvert: plastic bottles, plastic bags, towels and even clothes, which blocked the drainage of the culvert. After dredging, it has been drained smoothly.

　　In historical documents, it is often found that there are some records of roof leakage, wall collapse and courtyard water accumulation in the whole area of the Forbidden City. For example, in April of the eleventh year of Guangxu, the water accumulated from Donghuamen to Xihuamen was "several feet", but after the water accumulated, everyone's practice was to find the blocking point as soon as possible and clean it up, so that its drainage function could be quickly restored.
