The site of the Great Water Law is the main part of the scenic area of the Western Building in the Yuanmingyuan of Beijing. The main view of the Western Building Scenic Area is the artificial fountain, which is sometimes called the "water law". It is characterized by a large number, large momentum and strange ideas. The main formation of three large fountains, the Haitang and the Dashuifa, is very interesting, is the essence of Chinese and Western culture. The Dashuifa is adjacent to the Haitang, and is the most spectacular European-style fountain landscape in the park at the intersection of the north and south main axis of Changchun Garden and the west axis of the West Building. In 1860, the British and French coalition forces invaded Beijing and carried out the Great Palace of the Summer Palace. The British Army also set fire to it. Today, only a few marble pillars of the Great Water Law and the distant view stand there. Let us remember history and be beaten when we are backward. We who didn't know the road, walked around by ourselves, almost missed the most important water law, but fortunately continued to go in the direction of Haitang, so we didn't miss this water law. Although it is only a ruin, it can be imagined that it was once particularly brilliant.
