Tai Sui

Tai Sui is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tai Sui rather than just read about it. In short: Tai Sui is a Chinese name for stars directly opposite the planet Jupiter (Chinese: 木星; pinyin: Mùxīng) in its roughly 12-year orbital cycle. Personified as deities, they are important features of Chinese astrology, Feng Shui, Taoism, and to a lesser extent Chinese Buddhism.

Key takeaways

  • Tai Sui belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Tai Sui to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Tai Sui from memory before moving on to harder problems.

Reference excerpt

Tai Sui is a Chinese name for stars directly opposite the planet Jupiter (Chinese: 木星; pinyin: Mùxīng) in its roughly 12-year orbital cycle. Personified as deities, they are important features of Chinese astrology, Feng Shui, Taoism, and to a lesser extent Chinese Buddhism.

The 12 signs of the Chinese zodiac were based on divisions of the Jovian orbital cycle, rather than as in the western zodiac—the apparent motion of the sun relative to the celestial sphere. The star thought to oppose Jupiter during each year of the cycle was personified as a heavenly general or cycle god and was believed to help the Jade Emperor control the mortal world. By the Warring States period, the Tai Sui had become gods in the popular astrology; but no written records have been found of their worship prior to the Han dynasty. The earliest such record is found in Wang Chong's first-century Lunheng. There are several legends related to the Tai Sui, usually about people suffering disaster after disrespecting or ignoring them. Their number later quintupled to sixty based on combinations of the twelve divisions (reckoned using the earthly stems) with the five Chinese elements of fire, earth, metal, water, and wood. Each of the gods' features and attributes signifies the well-being or mishap of that year. For example, if the Tai Sui of a year holds a pen, this signifies political unrest for that particular year. On the other hand, a Tai Sui of the year who holds a spear or sword, signifies a need to work hard and excel in that year. Yin Jiao, leader of the sixty Taisui Xingjun (太歲星君) gods, doesn't govern any specific year in the 60-year cycle, and all of them were governed by one of the 60 subordinate Taisui. Yin Jiao in this context is called Taisui Tongling Yin Yuanshuai (太歲統領殷元帥, lit. Commander of the Tai Sui, General Yin). In Japan and Japanese folklore, however, "Taisui Xingjun" is just one singular god.

Practices

In Taoism, those whose birth signs or other features clash with the Tai Sui of the year face misfortunes or disturbances for that year. This applies in each year to people born under four of the twelve animal zodiac signs. In 2017 for example, it applied to people born in the years of the rat, rabbit, horse and rooster. In Taiwan, as the lunar year begins, people go to temples to seek peace and protection and drive away bad influences. This ceremony is known as "An Tai Sui" (安太歲) or pacifying the Tai Sui of the Year. In return, worshipers will receive a protective talisman from the temple which will give the person one year's spiritual protection. This tradition is also practiced by other overseas Chinese communities. In Chinese culture it has been traditionally considered taboo to build a house facing Taisui (or in the directly opposite direction) in the corresponding year of the Chinese zodiac. A similar belief is associated with moving houses and the line drawn through the old and new dwellings.

Worked examples

Example 1 — a first encounter with Tai Sui

Start with the simplest possible case. Write down what Tai Sui claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tai Sui before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tai Sui ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tai Sui

In research
Tai Sui appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Tai Sui in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Tai Sui is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomy in China, Chinese astrology, Stellar groupings, so understanding it makes those chapters shorter.
In everyday life
Look for Tai Sui outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
