Zi at the beginning of the cycle
The Hong Kong Observatory pairs the Rat with Zi. Animals repeat every twelve years, while ten stems and twelve branches form a sixty-year cycle. Two Rat years can therefore have different complete names. Museum sets of zodiac figures give that ordering a visible animal form.
A small, alert Rat also offers an image of resourcefulness in a New Year design. That cultural association can accompany a wish to notice opportunities, without making every person born in a Rat year share one personality. The calendar sign and a person’s experience remain different levels of description.
Rat years and their stem elements
The Gregorian year below is the year in which that lunar Rat year begins. Folk zodiac reckoning commonly runs from Lunar New Year to the next Lunar New Year, not from January 1. January and February births require the actual date to be checked.
Elements in this table follow the heavenly stem. They are not Na Yin classifications or a statement of the element personally needed in BaZi. Geng-Zi is called Metal Rat, while Ren-Zi is Water Rat; both retain the branch Zi.

How a Metal Rat can still have the Water branch Zi
In traditional branch associations, Zi belongs to Water. The Metal in Metal Rat comes from the stem Geng. Stem and branch can describe different elements without contradiction. A year label alone does not imply that its wearer should choose only Metal-themed materials.
The years 1960 and 2020 are both Geng-Zi; 1972 and 2032 are both Ren-Zi. The full designation repeats after sixty years. People born in the same year still have different months, days and hours, while BaZi considers the Day Master and complete pattern when discussing favorable elements.
Earth Rat similarly does not mean a person needs more Earth. A preferred color is a valid aesthetic choice; a personal composition uses the birth-chart energy pattern and luck cycles to give that preference a more specific context.
The Rat–Ox pair and Monkey–Rat–Dragon group
The traditional text San Ming Tong Hui describes Zi–Chou as a six-harmony pair and Shen–Zi–Chen as a three-harmony group. These correspond to Rat–Ox and Monkey–Rat–Dragon. They are relationship terms within a traditional system, not compulsory lists for marriage or business.

The text also treats a complete grouping and its conditions as significant. Seeing two compatible animal names does not establish a transformed Water configuration in anyone’s full chart. A relationship consultation considers more than the two year branches.
Zi–Wu is the Rat–Horse clash, while Zi and the 2027 branch Wei form a traditional harm relationship. Those terms need chart context; one label does not predict a breakup, financial loss or failure. The annual Rat page explains the 2027 relationship in its particular setting.
Lunar New Year and Li Chun are different boundaries
HKO gives Lunar New Year 2027 as February 6 and Li Chun as February 4 at 09:46, Hong Kong time, UTC+8. Between that solar-term moment and Lunar New Year, folk animal-year reckoning still belongs to the Horse year, while a Li Chun-based BaZi year pillar has moved to Ding-Wei.
For an overseas birth, Hong Kong clock time is not automatically local clock time. Original date, time, birthplace and calendar provide the necessary context. The year table is an initial reference; births near the transition need the complete record checked.
A zodiac gift can focus on learning, purposeful work or family protection. Existing bracelets are organized by intentions; they are not all Rat-shaped charms. Personal BaZi design brings favorable elements and annual wishes into a composition made for the wearer.
Questions & answers
Is everyone born in 2020 a Rat?
The date and boundary matter. A Rat year beginning in 2020 does not include every date from January 1; BaZi commonly also uses Li Chun for the year pillar.
Does Metal Rat mean a person is only Metal?
Metal names the stem, while Rat corresponds to the Water branch Zi. Month, day and hour add further information.
Does Rat–Ox harmony guarantee a marriage match?
No. It is a traditional branch relationship, not a substitute for complete charts or how two people actually relate.
Must a Rat wear only Water designs?
A zodiac label alone need not fix the materials. Favorable elements, annual wishes and wearing preferences give a more personal direction.
