The Chinese Zodiac, also known as the Chinese Zodiac, is twelve kinds of animals in China that match the twelve earthly branches according to the year of birth, including rats, cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs and pigs. The origin of the zodiac is related to animal worship. According to Qin bamboo slips unearthed in Yunmeng Sleeping Tiger Land in Hubei Province and Fangmatan in Tianshui, Gansu Province, a relatively complete zodiac system existed as early as the pre-Qin period. The earliest handed down document that recorded the same Chinese zodiac as today was Lun Heng written by Wang Chong in the Eastern Han Dynasty. The zodiac is an intuitive representation of the twelve earthly branches, namely, Zi (mouse), Ugly (ox), Yin (tiger), Mao (rabbit), Chen (dragon), Si (snake), Wu (horse), Wei (sheep), Shen (monkey), You (chicken) and Xu (chicken). In modern times, more people regard the zodiac as the mascot of the Spring Festival and become a symbol of entertainment and cultural activities. As a symbol of folk culture with a long history, the zodiac has left a large number of poems, Spring Festival couplets, paintings, calligraphy and paintings and folk arts and crafts depicting the image and symbolic significance of the zodiac throughout the ages. Apart from China, many countries in the world issue stamps of the zodiac during the Spring Festival to express their wishes for the New Year in China.
Tai sui, also known as meat ganoderma lucidum, is a legendary medicine that Qin Shihuang struggled to find for immortality. According to Shennong Materia Medica, "Meat Ganoderma lucidum is non-toxic, nourishing the middle energizer, benefiting essence, increasing intelligence, curing the knot in the chest, and strengthening the body for a long time." Shan Hai Jing, an ancient book, called Tai Sui "seeing meat, gathering meat and nourishing meat" and described it as "tired of eating and seeking recovery", which was a health food for ancient emperors.
