"The Classic of Mountains and Seas" is an ancient Chinese zhiwei book, the author is unknown, in the "Classic of Mountains and Seas" recorded distant ancient myths, mysterious religions, witchcraft, as well as a variety of geography, geology, anthropology, etc., in the ancient times when science and technology were not developed, the "Classic of Mountains and Seas" is an ancient encyclopedia.

Legend has it that in the distant mythological era, there is a "Fuso Tree" in the Eastern Sea, which is composed of two large mulberry trees that support each other, it is said that the sun goddess Xihe built for her son Jin Wu to drive up from here, and it is also a bridge connecting the Three Realms, but The Great Yi stands on the tree to shoot the sun, but unexpectedly breaks it, and the Three Realms have lost contact since then.
In the "Classic of Mountains and Seas", it is recorded that there is Fusang on the Tang Valley, bathed in ten days, and in the north of the black tooth, the "Great Wilderness East Classic" also contains: In the middle of the great wilderness, there is a mountain name called evil shaking. There is a butter on it, three hundred miles of pillars, and its leaves are like mustard. There is a valley known as the Wenyuan Valley. There are fumu on Yutani, one day to the end, one day out, all contained in Wu.
However, due to the absurdity of what is recorded in the Classic of Mountains and Seas, it has not been recognized, but the Fuso Sacred Tree mentioned in the Myth many times in the Classic of Mountains and Seas was discovered in Sichuan more than 30 years ago.
In 1929, on the south bank of the Yazi River in the northwest of Guanghan City, Sichuan Province, a farmer was digging ditches in the car, and by chance he found a pit of jade tools, but because it was in the war period at that time, the excavation of cultural relics dragged on until 1963, and a joint archaeological team composed of the Sichuan Provincial Museum and the History Department of Sichuan University inspected the site.
They named this site "Sanxingdui Site", due to limited technical conditions, Sanxingdui excavation work, before and after up to 20 years, of which the excavation is representative of bashu culture and bronze culture, in the history of Bashu region has been relatively closed, and there is little communication with the Central Plains.
However, the excavation of Sanxingdui cultural relics has refreshed the historians' understanding of Bashu, and the history of Sanxingdui belongs to the same period as the Liangzhu culture, which can be pushed back to 5,000 years ago, that is, a civilization formed before the Xia Shang, and the bronze artifacts unearthed by Sanxingdui are as high as more than a thousand pieces.
One of the statues alone is 2.62 meters high, weighs more than 180 pounds, the portrait wears a high crown of animal face, and holds the sacrificial shape of the object, this tall bronze statue, even in the Shang Dynasty civilization is unique, in addition to the strange portrait, the highest is the bronze sacred tree.
However, due to the excavations are fragments, the trunk is broken into 3 sections, the branches are broken into 18 sections, some of the ornaments on the tree are also broken into pieces, in order to restore the sacred tree, the archaeological team spent a total of 10 years to restore the original appearance of the sacred tree, the bronze sacred tree is 3.96 meters high, and the trunk is 3.84 meters high.
The sacred tree has a total of three layers of branches, three branches on each layer, and on top of the three branches stands a bird, a total of nine, each shape is high and upward, posing a look that may fly away at any time, the bronze tree unearthed by Sanxingdui coincides with the "Fuso Tree" in the "Classic of Mountains and Seas".
However, there is a dragon under the bronze tree, in ancient times, the dragon and the tree are connected together, is their common "pointing to the time" feature, generally used for measuring the sky, the measurement of the sky is the so-called prayer for rain, protection of crops, Guotai Min'an, Sanxingdui bronze cultural relics also reflect the ancient Shu people in the early days to worship the god of nature, but the cultural relics of Sanxingdui still maintain a full sense of mystery.
