Niusu and Nvsu, located on both sides of the Milky Way, evolved the story of Cowherd and Weaver Girl. Niusu is also called Altair, Altair and Polaris. In the east of the Milky Way, there are six stars, three of which seem to be walking alone with their bags on their backs. The guest house is the third one of the seven nights in Xuanwu, also known as Vega and William Sunsing Hidalgo. In the west of the Milky Way, there are three stars in an equilateral triangle, like a woven shuttle. In the Book of Songs Dadong, there are two stars: "Yang and the Weaver Girl are fragrant all day long." Even if the weaver girl is busy, she can't knit a stripe well. You don't want to take the box. "It means that Vega with three horns moves back and forth seven times a day. Although I moved seven times, I couldn't weave a good pattern of cloth brocade. Look at the morning glory shining, but it can't be used to drive. In the Han Dynasty, Niu Nv and Er Xing were completely personified. " Nineteen Ancient Poems: "Far away, Altair, Hehan girl. Skillful hands, make a loom. There is no chapter all day, and tears are pouring down. The river is clear and shallow, with many differences. When Ying Ying sleeps, her pulse is silent. "The poem describes the sadness of the Weaver Girl looking at the morning glory across the Milky Way and shows the pain when love is tortured." It's almost as difficult for friends to meet each other. As for the stars in the morning and evening, this is a poem in Du Fu's "To Wei Ba Chu Shi", which means that he and his close friend Wei Ba Chu Shi were not allowed to meet before, just like staying in a hotel or business hotel. "Shen" and "Shang" are the names of the stars. "Betelgeuse" is the seventh of the seven lodgings of the Western White Tiger, and "Shangsu" is the fifth of the seven lodgings of the Oriental Black Dragon, which is another name for Shinjuku. These two stars, one in the east, one in the west, just rose from the horizon, and the other in the west, have fallen from the horizon and will never meet each other. There is a related story in Zuo Zhuan. Di Ku, the ancient emperor, had two sons, one named Quebo and the other named Stone God. The two brothers quarreled all day, and finally came to the point of fighting with each other. Di Ku had to separate the two brothers, and Quebo was sent to Shangqiu, where he became the ancestor of Shang Dynasty, taking Shang Xing as his home star. Stone God was sent to Daxia and became the ancestor of Xia Dynasty, with Canxing as the family star. Since then, the two brothers have never met again.
The ancients thought Sirius was the star of evil, and it also invaded and plundered. Sirius, also known as the dog star, is the star of Su Jing, and is the first of the seven nights of southern Suzaku. Su Shi has a saying in Jiangchengzi: "You can bow like a full moon, look at the northwest and shoot Sirius." Among them, "Sirius" refers to Liao State and Xixia State.
Many people use "fire in July" to describe the heat in summer, which is a misunderstanding. The Book of Songs in July: "July is full of fire, and clothes are given in September." The "fire" mentioned here is the "mind element" of the five nights in Oriental Black Dragon. Because of its blood red color, it is also called "Big Mars". "Streaming fire" means that Mars is gradually going down to the west, but when the summer heat recedes, it will be very cold.
"There are nights in the sky and continents on the ground." The ancients also used the directions of 28 nights in the sky to distinguish the areas on the ground. A certain area on the ground is pointed by a star, which is called the division of a certain place within a star. Wang Bo's Preface to Wang Tengting: "Zhang Yu is an old county, and Hongdu is a new house. The stars spread their wings and meet Lu Heng. " Wing and Chiba are the sixth and seventh lodging of Suzaku in the south, respectively, which means Hongzhou belongs to the area corresponding to the second lodging of Wing Chiba. Li Bai's Shu Dao Nan: Panting, we brush Orion and cross Jingxing Star. Betelgeuse is the dividing line between Qin and Shu, so it is said that "Qin has a good calendar".
