Question 1

How do you pronounce 巳?

Accepted Answer

巳 is pronounced sì in modern Standard Mandarin, with a falling fourth tone. It sounds like the number four, 四.

Question 2

Which number is Si among the Earthly Branches?

Accepted Answer

Si is the sixth Earthly Branch. It follows Chen (辰), the Dragon branch, and precedes Wu (午), the Horse branch.

Question 3

Is Si the Snake zodiac sign?

Accepted Answer

Si is the formal branch paired with the Snake (蛇) in the 12-animal zodiac. The two are closely linked, but Si also marks hours, months, years, and directions where no literal animal is intended.

Question 4

What time is Si hour?

Accepted Answer

Si hour is commonly converted as 09:00–11:00. This is the standard modern two-hour mapping; historical local solar time and changing timekeeping practices should not be treated as identical to today’s standard clock.

Question 5

When does Si month begin and end?

Accepted Answer

In common solar-term month systems, Si month begins at Lixia and ends when Mangzhong arrives. It usually falls around May 5/6 to June 5/6, but the exact instant depends on the year and time zone.

Question 6

Is Si month the same as the fourth lunar month?

Accepted Answer

No. They are traditionally associated, but the fourth lunar month begins with a lunar-month boundary, while the Si solar month begins at Lixia. Their dates can differ by days or weeks.

Question 7

What direction is Si?

Accepted Answer

Si is south-southeast, centered near 150°. In the common modern Twenty-Four Mountains division, the Si mountain spans 142.5°–157.5° and is separate from the neighboring Xun mountain.

Question 8

What is the five element of Si?

Accepted Answer

Si is associated with Fire in a widely used traditional correspondence table and is commonly classified as a yin branch. This is a cosmological category, not a physical element inside the character.

Question 9

What are the hidden stems in Si?

Accepted Answer

A common Bazi rule gives Si the hidden stems Bing (丙), Wu (戊), and Geng (庚). Hidden stems are part of a later interpretive framework; fixed percentage weights are not universal.

Question 10

What does Si–Hai clash (巳亥冲) mean?

Accepted Answer

Si and Hai form one of the Six Clash pairs in later branch-relationship tables and occupy approximately opposite directions. The label identifies a structural opposition; personal predictions require a much larger interpretive system.

Question 11

What are Si–You–Chou and Si–Wu–Wei?

Accepted Answer

Si–You–Chou (巳酉丑) is the Three Harmony set associated with Metal, while Si–Wu–Wei (巳午未) is the Three Meetings summer/fire set. They are traditional relationship models, not automatic signs of wealth, fame, or support.

Question 12

What is an Yisi (乙巳) year?

Accepted Answer

Yisi combines the yin Wood stem Yi (乙) with the Snake branch Si (巳). It is one position in the 60-step sexagenary cycle; 1905, 1965, and 2025 are Yisi years.

Question 13

What is the difference between 巳, 已, and 己?

Accepted Answer

巳 is sì, the sixth Earthly Branch; 已 is yǐ, commonly “already”; 己 is jǐ, “self” and also the sixth Heavenly Stem. Their shapes are similar, but their readings and functions differ.

Question 14

Can one Si determine personality, health, or fate?

Accepted Answer

A single Si only identifies one branch position. Even within Bazi, interpretation depends on all four pillars, season, interactions, timing rules, and school-specific methods; the branch alone is not a complete personal reading.
