What does a white star mean during the day?

After Wu Zetian entered the palace and was named a gifted scholar, it was not so smooth sailing, nor did it develop as her mother Yang Peony hoped. At that time, another astrologer, who was just as famous as Yuan Tiangang, asked Li to observe the astronomical phenomena in the Imperial Palace, and found that Taibai Star appeared in the daytime for several days in a row, so he divined a divination. This divination is so strange that Li dare not ignore it. He said to emperor Taizong, "mistress should be rich." At the same time, there is a manuscript "Secret Record" circulating in Chang 'an, which reads: "After the three generations of Tang Dynasty, Queen Wu Ying won the world."

Chang Geng Xing is Taibai Xing. There is an old saying: work at sunrise, and rest at the age of ten. Taibai Star, commonly known as Seven Stars, is the brightest star before the sun comes out, indicating that the sun is coming out soon.

Taibai Venus only appeared in novels of Ming and Qing Dynasties, and most of them gave him the name of Li Changgeng, which was purely perfunctory from the traditional astrology. In ancient times, the standard name of Venus among the five major planets was "Taibai", which belonged to the west in the traditional stars, while the west was gold in the five elements. Therefore, it was not until the Ming Dynasty that the name of Venus officially appeared. It was called Chang Gung because Venus had an ancient name "Chang Gung". This is because Venus appeared in the western sky every year in the dark. Li's surname may be the cause of Li Bai, or it may be attached to Lao Zi's surname. It's hard to say. In a word, Li Changgeng, the white Venus, is probably the way it is.
