Xinhuanet Tianjin, February 6 (Reporter Zhou Runjian, Cai) Ye Chunsheng, a professor in the Chinese Department of Sun Yat-sen University, said that the zodiac should start from February 4, that is, beginning of spring. In this regard, Su Yi, chairman of Tianjin Astronomical Society and professor of Nankai University, pointed out that this statement does not conform to the traditional and recognized laws, and the zodiac should be counted from the first day of the first month.

Su Yi told reporters that beginning of spring is one of the 24 solar terms, and the solar term is a moment, which depends on the annual movement of the sun. The determination of the first month of the year is based on neutral rain. The solar term in beginning of spring precedes the rain, probably at the end of the year and the beginning of the year, and beginning of spring is not the beginning of the year. Some years have beginning of spring at both ends (so-called "double-headed spring"), such as 2006; There is no beginning of spring in some years, such as 2002. Therefore, it is unreasonable to start the Lunar New Year in beginning of spring.

Chronology of trunk and branch is one of the traditional chronologies of trunk and branch in ancient China: chronology, chronology, chronology (commonly known as "birthday"). In ancient times, astrologers used twelve kinds of animals to match the twelve earthly branches. Children are rats, ugly cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs and pigs, which are called the "Twelve Zodiacs". Life is about something in a certain year, such as mice born in childhood, cows born in ugly years and so on. Therefore, when you were born in the year of Xu Bing, you should be a dog, and dogs should not be counted from beginning of spring, but from the beginning of the year.

In addition, the World Centennial Calendar compiled by Purple Mountain Observatory of Chinese Academy of Sciences clearly stipulates that children born from June 29, 2006 to February 7, 2007 (that is, Xu Bingnian) should belong to dogs.
