Some cultures assign different animals: Vietnam replaces the Ox and Rabbit with the water buffalo and cat, respectively; Tibet replaces the Rooster with the bird. In the traditional Kazakh version of the 12 year animal cycle (Kazakh : мүшел, müşel), the Dragon is substituted by a snail (Kazakh : ұлу, ulw), and the Tiger appears as a leopard (Kazakh : барыс, barıs).

The 24 cardinal directions (ancient Chinese convention places the south (red) at the top).

Though Chinese has words for the four cardinal directions, Chinese mariners and astronomers/astrologers preferred using the 12 directions of the Earthly Branches, which is somewhat similar to the modern-day practice of English-speaking pilots using o'clock for directions. Since 12 points were not enough for sailing, 12 midpoints were added. Instead of combining two adjacent direction names, they assigned new names:

Advanced mariners such as Zheng He used 48-point compasses. An additional midpoint was called by a combination of its two closest basic directions, such as 丙午 (bǐngwǔ) for the direction of 172.5°, the midpoint between (bǐng), 165°, and (), 180°.

Current usage

The terrestrial branches are still commonly used nowadays in Chinese counting systems similar to the way the alphabet is used in English. For example, names in legal documents and contracts where English speakers would use K, L, M, etc. Korea and Japan also use terrestrial branches on legal documents in this way.

Since the celestial stems and terrestrial branches combined only consist of 22 characters, the four final letters – W, X, Y, and Z – cannot be represented by any of the celestial stems and terrestrial branches, and those four letters are represented by ‘物’, ‘天’, ‘地’, and ‘人’, respectively, instead. [4]

In case of upper-case letters, the radical of ‘口’ (the ‘mouth’ radical) may be added to the corresponding terrestrial branch or any of ‘物’, ‘天’, ‘地’, and ‘人’ to denote an upper-case letter. [5]

Chinese calendar Lunisolar calendar from China

The traditional Chinese calendar (also known as the Agricultural Calendar [農曆; 农历; Nónglì; 'farming calendar'], Former Calendar [舊曆; 旧历; Jiùlì], Traditional Calendar [老曆; 老历; Lǎolì], is a lunisolar calendar which identifies years, months, and days according to astronomical phenomena. In China, it is defined by the Chinese national standard GB/T 33661–2017, "Calculation and Promulgation of the Chinese Calendar", issued by the Standardization Administration of China on May 12, 2017.

Ecliptic Apparent path of the Sun on the celestial sphere

The ecliptic is the plane of Earth's orbit around the Sun. From the perspective of an observer on Earth, the Sun's movement around the celestial sphere over the course of a year traces out a path along the ecliptic against the background of stars. The ecliptic is an important reference plane and is the basis of the ecliptic coordinate system.

Zodiac Area of the sky divided into twelve signs

The zodiac is a belt-shaped region of the sky that extends approximately 8° north or south of the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year. The paths of the Moon and visible planets are within the belt of the zodiac.

Celestial sphere Imaginary sphere of arbitrarily large radius, concentric with the observer

In astronomy and navigation, the celestial sphere is an abstract sphere that has an arbitrarily large radius and is concentric to Earth. All objects in the sky can be conceived as being projected upon the inner surface of the celestial sphere, which may be centered on Earth or the observer. If centered on the observer, half of the sphere would resemble a hemispherical screen over the observing location.

Chinese constellations Groupings used in Chinese astrology

Traditional Chinese astronomy has a system of dividing the celestial sphere into asterisms or constellations, known as "officials".

Chinese astrology Astrology based on Chinese astronomy

Chinese astrology is based on the traditional astronomy and calendars. Chinese astrology came to flourish during the Han Dynasty.

Armillary sphere Model of objects in the sky consisting of a framework of rings

An armillary sphere is a model of objects in the sky, consisting of a spherical framework of rings, centered on Earth or the Sun, that represent lines of celestial longitude and latitude and other astronomically important features, such as the ecliptic. As such, it differs from a celestial globe, which is a smooth sphere whose principal purpose is to map the constellations. It was invented separately first in ancient China during the 4th century BC and ancient Greece during the 3rd century BC, with later uses in the Islamic world and Medieval Europe.

The ten Heavenly Stems or Celestial Stems are a Chinese system of ordinals that first appear during the Shang dynasty, c. 1250 BC, as the names of the ten days of the week. They were also used in Shang-period ritual as names for dead family members, who were offered sacrifices on the corresponding day of the Shang week. The Heavenly Stems were used in combination with the Earthly Branches, a similar cycle of twelve days, to produce a compound cycle of sixty days. Subsequently, the Heavenly Stems lost their original function as names for days of the week and dead kin, and acquired many other uses, the most prominent and long lasting of which was their use together with the Earthly Branches as a 60-year calendrical cycle. The system is used throughout East Asia.

Pig (zodiac) Sign of the Chinese zodiac

The Pig or sometimes translated as the Boar is the twelfth of the 12-year cycle of animals which appear in Chinese zodiac, in relation to the Chinese calendar and system of horology, and paralleling the system of ten Heavenly Stems and twelve Earthly Branches. Although the term "zodiac" is used in the phrase "Chinese zodiac", there is a major difference between the Chinese usage and Western astrology: the zodiacal animals do not relate to the zodiac as the area of the sky that extends approximately 8° north or south of the ecliptic, the apparent path of the Sun, the Moon, and visible planets across the celestial sphere's constellations, over the course of the year.

Ox (zodiac) Sign of the Chinese zodiac

The Ox is the second of the 12-year periodic sequence (cycle) of animals which appear in the Chinese zodiac related to the Chinese calendar, and also appears in related calendar systems. The Chinese term translated here as ox is in Chinese niú , a word generally referring to cows, bulls, or neutered types of the bovine family, such as common cattle or water buffalo. The zodiacal ox may be construed as male, female, neutered, hermaphroditic, and either singular or plural. The Year of the Ox is also denoted by the Earthly Branch symbol chǒu. The term "zodiac" ultimately derives from an Ancient Greek term referring to a "circle of little animals". There are also a yearly month of the ox and a daily hour of the ox. Years of the oxen (cows) are cyclically differentiated by correlation to the Heavenly Stems cycle, resulting in a repeating cycle of five years of the ox/cow, each ox/cow year also being associated with one of the Chinese wǔxíng, also known as the "five elements", or "phases": the "Five Phases" being Fire, Water, Wood, Metal, and Earth. The Year of the Ox follows after the Year of the Rat which happened in 2020 and is then followed by the Year of the Tiger, which happened in 2022.

Rat (zodiac) Sign of the Chinese zodiac

The Rat or Mouse is the first of the repeating 12-year cycle of animals which appear in the Chinese zodiac, constituting part of the Chinese calendar system. The Year of the Rat in standard Chinese is ; the rat is associated with the first branch of the Earthly Branch symbol (), which starts a repeating cycle of twelve years. The Chinese word shǔ refers to various small rodents (Muroidea), such as rats and mice. The term "zodiac" ultimately derives from an Ancient Greek term referring to a "circle of little animals". There are also a yearly month of the rat and a daily hour of the rat. Years of the rat are cyclically differentiated by correlation to the Heavenly Stems cycle, resulting in a repeating cycle of five years of the rat, each rat year also being associated with one of the Chinese wu xing, also known as the "five elements", or "phases": the "Five Phases" being Fire, Water, Wood, Metal, and Earth.

Tianlong Mythological creature

Tianlong is a flying dragon in Chinese mythology, a star in Chinese astrology, and a proper name.

The sexagenary cycle, also known as the Stems-and-Branches or ganzhi, is a cycle of sixty terms, each corresponding to one year, thus a total of sixty years for one cycle, historically used for recording time in China and the rest of the East Asian cultural sphere. It appears as a means of recording days in the first Chinese written texts, the Shang oracle bones of the late second millennium BC. Its use to record years began around the middle of the 3rd century BC. The cycle and its variations have been an important part of the traditional calendrical systems in Chinese-influenced Asian states and territories, particularly those of Japan, Korea, and Vietnam, with the old Chinese system still in use in Taiwan, and to a lesser extent, in Mainland China.

Tai Sui is a Chinese term for the stars directly opposite the planet Jupiter during its roughly 12-year orbital cycle. Personified as deities, they are important features of Chinese astrology, Feng Shui, Taoism, and Chinese Buddhism to a lesser extent.

The Four Pillars of Destiny, as known as "Ba-Zi", which means "eight characters" or "eight words" in Chinese, is a Chinese astrological concept that a person's destiny or fate can be divined by the two sexagenary cycle characters assigned to their birth year, month, day, and hour. This type of cosmological astrology is also widely used in both South Korea and Japan.

In Chinese astrology, the symbolic stars, also translated as star spirits or calendar spirits, represent beneficial and baleful influences believed to be present during particular times, typically in relation to the specific positions and interactions of the heavenly stems and earthly branches used in traditional Chinese timekeeping and the sexagenary cycle.

A tropical year is the time that the Sun takes to return to the same position in the sky of a celestial body of the Solar System such as the Earth, completing a full cycle of seasons; for example, the time from vernal equinox to vernal equinox, or from summer solstice to summer solstice. It is the type of year used by tropical solar calendars. The solar year is one type of astronomical year and particular orbital period. Another type is the sidereal year, which is the time it takes Earth to complete one full orbit around the Sun as measured with respect to the fixed stars, resulting in a duration of 20 minutes longer than the tropical year, because of the precession of the equinoxes.

Wen Wang Gua is a method of interpreting the results of I Ching divination that was first described in writing by Jing Fang in Han dynasty China. It is based on correlating trigrams to the Celestial Stems and Earthly Branches of the Chinese calendar, and then using the stem and branch elements to interpret the lines of the trigrams and hexagrams of the I Ching. The method is popular in South East Asia. It is known by various names: refers to the fact that it interprets the meaning of six symbols; the Najia method, indicates its logic of elemental values derived from the Chinese calendar; Wu Xing Yi ; or Wen Wang Ke.

Chinese theology Overview of the topic

Chinese theology, which comes in different interpretations according to the classic texts and the common religion, and specifically Confucian, Taoist and other philosophical formulations, is fundamentally monistic, that is to say it sees the world and the gods of its phenomena as an organic whole, or cosmos, which continuously emerges from a simple principle. This is expressed by the concept that "all things have one and the same principle". This principle is commonly referred to as Tiān 天, a concept generally translated as "Heaven", referring to the northern culmen and starry vault of the skies and its natural laws which regulate earthly phenomena and generate beings as their progenitors. Ancestors are therefore regarded as the equivalent of Heaven within human society, and therefore as the means connecting back to Heaven which is the "utmost ancestral father". Chinese theology may be also called Tiānxué 天學, a term already in use in the 17th and 18th century.

[In contrast to the God of Western religions who is above the space and time] the God of Fuxi, Xuanyuan and Wang Yangming is under in our space and time. ... To Chinese thought, ancestor is creator.
