Chinese astrology in the context of Tai Sui

Taoism or Daoism (/ˈtaʊ.ɪzəm/ , /ˈdaʊ.ɪzəm/ ) is a philosophical and religious tradition indigenous to China, emphasizing harmony with the Tao 道 (Chinese: 道; pinyin: dào, pronounced (IPA): /tɑʊ̯/ (Chinese)). With a range of meaning in Chinese philosophy, translations of Tao include 'way', 'road', 'path', or 'technique', generally understood in the Taoist sense as an enigmatic process of transformation ultimately underlying reality. Taoist thought has informed the development of various practices within the Taoist tradition, ideation of mathematics and beyond, including forms of meditation, astrology, qigong, feng shui, and internal alchemy. A common goal of Taoist practice is self-cultivation, a deeper appreciation of the Tao, and more harmonious existence. Taoist ethics vary, but generally emphasize such virtues as effortless action, naturalness, simplicity, and the three treasures of compassion, frugality, and humility.

The core of Taoist thought crystallized during the early Warring States period (c. 450 – c. 300 BCE), during which the epigrammatic Tao Te Ching and the anecdotal Zhuangzi—widely regarded as the fundamental texts of Taoist philosophy—were largely composed. They form the core of a body of Taoist writings accrued over the following centuries, which was assembled by monks into the Daozang canon starting in the 5th century CE. Early Taoism drew upon diverse influences, including the Shang and Zhou state religions, Naturalism, Mohism, Confucianism, various Legalist theories, as well as the I Ching and Spring and Autumn Annals.

Wuxing (Chinese: 五行; pinyin: wǔxíng; Jyutping: Ng Hang), translated as Five Moving Ones, Five Circulations, Five Types of Energy, Five Elements, Five Transformations, Five Phases or Five Agents, is a fivefold conceptual scheme used in many traditional Chinese fields of study to explain a wide array of phenomena, including terrestrial and celestial relationships, influences, and cycles, that characterise the interactions and relationships within science, medicine, politics, religion and social relationships and education within Chinese culture.

The Five Moving Ones are traditionally associated with the classical planets: Mars, Mercury, Jupiter, Venus, and Saturn as depicted in the etymological section below. In ancient Chinese astronomy and astrology, that spread throughout East Asia, was a reflection of the seven-day planetary order of Fire, Water, Wood, Metal, Earth. When in their "heavenly stems" generative cycle as represented in the below cycles section and depicted in the diagram above running consecutively clockwise (Wood, Fire, Earth, Metal, Water). When in their overacting destructive arrangement of Wood, Earth, Water, Fire, Metal, natural disasters, calamity, illnesses and disease will ensue.

Astrology is a range of divinatory practices, recognized as pseudoscientific since the 18th century, that propose that information about human affairs and terrestrial events may be discerned by studying the apparent positions of celestial objects. Different cultures have employed forms of astrology since at least the 2nd millennium BCE, these practices having originated in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications.

Most, if not all, cultures have attached importance to what they observed in the sky, and some—such as the Hindus, Chinese, and the Maya—developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th–17th century BCE Mesopotamia, from where it spread to Ancient Greece, Rome, the Islamic world, and eventually Central and Western Europe. Contemporary Western astrology is often associated with systems of horoscopes that purport to explain aspects of a person's personality and predict significant events in their lives based on the positions of celestial objects; the majority of professional astrologers rely on such systems.

Chinese star names (Chinese: 星名, xīng míng) are named according to ancient Chinese astronomy and astrology. The sky is divided into star mansions (星宿, xīng xiù, also translated as "lodges") and asterisms (星官, xīng guān). The ecliptic is divided into four sectors that are associated with the Four Symbols, guardians in Chinese mythology, and further into 28 mansions. Stars around the north celestial pole are grouped into three enclosures (垣, yuán). The system of 283 asterisms under the Three Enclosures and Twenty-Eight Mansions was established by Chen Zhuo of the Three Kingdoms period, who synthesized ancient constellations and the asterisms created by early astronomers Shi Shen, Gan De and Wuxian. Since the Han and Jin dynasties, stars have been given reference numbers within their asterisms in a system similar to the Bayer or Flamsteed designations, so that individual stars can be identified. For example, Deneb (α Cyg) is referred to as 天津四 (Tiān Jīn Sì, the Fourth Star of Celestial Ford).

In the Qing dynasty, Chinese knowledge of the sky was improved by the arrival of European star charts. Yixiang Kaocheng, compiled in mid-18th century by then deputy Minister of Rites Ignaz Kögler, expanded the star catalogue to more than 3000 stars. The newly added stars (增星, zēng xīng) were named as 增一 (zēng yī, 1st added star), 增二 (zēng èr, 2nd added star) etc. For example, γ Cephei is referred to as 少衛增八 (Shào Wèi Zēng Bā, 8th Added Star of Second Imperial Guard). Some stars may have been assigned more than one name due to the inaccuracies of traditional star charts.

A horoscope (or other commonly used names for the horoscope in English include natal chart, astrological chart, astro-chart, celestial map, sky-map, star-chart, cosmogram, vitasphere, radical chart, radix, chart wheel or simply chart) is an astrological chart or diagram representing the positions of the Sun, Moon, planets, astrological aspects and angles at the time of an event, such as the moment of a person's birth. The word horoscope is derived from the Greek words ōra and scopos meaning "time" and "observer" (horoskopos, pl. horoskopoi, or "marker(s) of the hour"). It is claimed by proponents of astrology that a horoscope can be used as a method of divination regarding events relating to the point in time it represents, and it forms the basis of the horoscopic traditions of astrology, although practices surrounding astrology have been recognized as pseudoscientific since the 18th century. Horoscope columns are often featured in print and online newspapers.

In common usage, horoscope often refers to an astrologer's interpretation, usually based on a system of solar Sun sign astrology, based strictly on the position of the Sun at the time of birth or on the calendar significance of an event, as in Chinese astrology. In particular, many newspapers and magazines carry predictive columns, written in prose that may be written more for increasing readership than tied directly to the Sun or other aspects of the Solar System, allegedly based on celestial influences in relation to the zodiacal placement of the Sun on the month of birth, cusp (two days before or after any particular sign, an overlap), or decant (the month divided into three ten-day periods) of the person's month of birth, identifying the individual's Sun sign or "star sign" based on the tropical zodiac.

The Earthly Branches (also called the Terrestrial Branches or the 12-cycle) are a system of twelve ordered symbols used throughout East Asia. They are indigenous to China, and are themselves Chinese characters, corresponding to words with no concrete meaning other than the associated branch's ordinal position in the list.

Cultural applications of the Branches include a dating system known as the sexagenary cycle, and their use in Chinese astrology. They are associated with the ten Heavenly Stems in Chinese calendars, and in Taoist practice.

The Xiuzhen tu (simplified Chinese: 修真图; traditional Chinese: 修真圖; pinyin: Xiūzhēn tú; Wade–Giles: Hsiu-chen t'u) is a Daoist diagram of the human body illustrating the preventative Chinese medical principles called Neidan 'internal alchemy', incorporating Chinese astrology, and cosmology.

In Western astrology, astrological signs are the zodiac, twelve 30-degree sectors that are crossed by the Sun's 360-degree orbital path as viewed from Earth in its sky. The signs enumerate from the first day of spring, known as the First Point of Aries, which is the vernal equinox. The astrological signs are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. The Western zodiac originated in Babylonian astrology, and was later influenced by the Hellenistic culture. Each sign was named after a constellation the sun annually moved through while crossing the sky. This observation is emphasized in the simplified and popular sun sign astrology. Over the centuries, Western astrology's zodiacal divisions have shifted out of alignment with the constellations they were named after by axial precession of the Earth while Hindu astrology measurements correct for this shifting. Astrology (i.e. a system of omina based on celestial appearances) was developed in Chinese and Tibetan cultures as well but these astrologies are not based upon the zodiac but deal with the whole sky.

Astrology is a pseudoscience. Scientific investigations of the theoretical basis and experimental verification of claims have shown it to have no scientific validity or explanatory power. More plausible explanations for the apparent correlation between personality traits and birth months exist, such as the influence of seasonal birth in humans.
