The Ox is the second animal in the Vietnamese and Chinese zodiac, and in Vietnam it is a water buffalo: Sửu, or con Trâu. Recent Ox years were 1985, 1997, 2009 and 2021, and the next one begins in 2033. Traditional readings link the sign with patience, reliability and the quiet strength to keep going when others stop. They also warn of its shadow side: a firmness that can harden into rigidity, and a work ethic that forgets to rest.
As with every animal sign, your year follows the traditional lunisolar calendar. If your birthday falls in January or February, check when Tet arrived that year before settling on your sign.

Ox quick facts

The full Vietnamese order is Rat, Buffalo, Tiger, Cat, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog and Pig. The Cat takes the fourth place that the Rabbit holds in Chinese tradition, so the cycle still has twelve signs. Our Vietnamese zodiac signs page introduces each of them.
Ox or water buffalo?
English sources almost always say “Ox”, but the Vietnamese animal is the water buffalo, the broad-horned, mud-loving animal that has pulled ploughs through flooded rice fields for generations. Vietnam Airlines’ guide to the Vietnamese horoscope notes this local naming. The branch, Sửu, is the same in both traditions; only the animal chosen to represent it differs.
The choice says a lot. In a rice-growing culture, the buffalo was not a symbol of abstract strength but a working partner and often the most valuable thing a farming household owned. An old Vietnamese saying puts it plainly: “Con trâu là đầu cơ nghiệp”, the buffalo is the foundation of the family’s livelihood. Children grew up riding buffalo to the fields, and the animal turns up in folk songs, poems and village paintings as a picture of patient, shared labour. Hai Phong’s Đồ Sơn buffalo festival is one of the better-known regional traditions still built around the animal.
So when Vietnamese families talk about someone born in a Sửu year, the image is less a stubborn bull and more a steady companion who shows up every day and gets the field ploughed.
Ox years and the Tet boundary
Ox years repeat every twelve years:
- 1961, 1973, 1985, 1997, 2009, 2021
- Next: 2033
These Gregorian years are shorthand, not exact date ranges. Each lunar year starts at Tet, which shifts in January or February. A baby born in the first days of January 1997 belongs to the previous year, the Rat, because Tet never comes that early. February birthdays need a check against that year’s Tet date. The Hong Kong Observatory explains how these year boundaries and the stem-and-branch system work. For a Vietnamese birth date, it is best to confirm with a Vietnamese lunar calendar, since Vietnam and China calculate their calendars for different time zones.
You may also hear that the year starts in early February at the Beginning of Spring (Lập Xuân). That convention belongs to some BaZi (Four Pillars) systems. The animal most people mean in everyday talk, and the one celebrated at Tet, follows the Lunar New Year.
The five Ox types by element
Each traditional year pairs a heavenly stem with an earthly branch. After checking the Tet boundary, find the stem element from the last digit of the zodiac year label: 0 or 1 Metal, 2 or 3 Water, 4 or 5 Wood, 6 or 7 Fire, 8 or 9 Earth. Animals repeat every twelve years, so any single element-animal pairing, such as Fire Ox, comes back every sixty.
Note the difference between this year element and the Ox’s fixed element. The Sửu branch always belongs to Earth. An “Earth Ox” year, such as 2009, simply doubles that association.
| Type | Vietnamese name | Year labels | Traditional flavour |
|---|---|---|---|
| Wood Ox | Ất Sửu | 1925, 1985 | Principled and protective of others; more restless than other Oxen |
| Fire Ox | Đinh Sửu | 1937, 1997 | Driven and outspoken; reasoned, though quick to judge |
| Earth Ox | Kỷ Sửu | 1949, 2009 | Careful and dependable; a strong sense of responsibility |
| Metal Ox | Tân Sửu | 1961, 2021 | Dedicated and busy; firm in its views |
| Water Ox | Quý Sửu | 1913, 1973, 2033 | Observant and resilient; more flexible than the typical Ox |
Older English pages sometimes write “Gold Ox”. The Vietnamese Kim covers both metal and gold, so it is the same type.
Strengths and challenges
These descriptions come from traditional interpretation. Read them as a cultural portrait that can prompt reflection, not as a verdict on who you are or what will happen to you.
Patience is the trait most often attached to the Ox. In folk readings, this is someone comfortable with slow progress, who trusts that steady effort adds up. Reliability follows naturally: if an Ox-year friend says they will help you move house, the traditional picture says they will arrive early and stay until the last box is in. The sign is also linked with thoroughness, a preference for doing a job properly over doing it quickly, and with loyalty that deepens over years rather than weeks.
The challenges are the same qualities pushed too far. Patience can become reluctance to change course even when the ground has shifted. A strong sense of how things should be done can turn into rigidity, and others may experience that firmness as stubbornness or a closed door. The buffalo image carries a warning too. An animal that keeps pulling without complaint can be overloaded without anyone noticing, including itself. Traditional readings often describe the Ox as someone who takes on more, says little, and carries tiredness quietly until it shows.
A fair summary: the Ox’s endurance is real, but endurance is not the same as wisdom about where to spend it.
Relationships and work
Consider a hypothetical. Picture an Ox-year colleague who is the person everyone relies on to finish a difficult report. The traditional profile suggests they will deliver, carefully and on time. It also suggests they may never mention that they worked three weekends to do it, and may resist when a manager proposes a faster, rougher approach. Both halves of that picture are worth noticing.
The qualities linked with the Ox fit work that rewards care and consistency: craft and making, engineering, finance and accounting, agriculture, healthcare, building and long-term project management. Anyone can thrive anywhere, of course. If the Ox description resonates, these questions may be more useful than a career list:
- Which of my commitments am I keeping out of habit rather than because they still matter?
- When someone suggests a new method, do I test it before rejecting it?
- Who knows how much I am actually carrying right now?
In relationships, the Ox is traditionally described as slow to open up and steady once committed. Folklore groups it with the Snake and Rooster, pairs it with the Rat, and places it opposite the Goat. These associations are part of Vietnamese and Chinese custom and often come up lightheartedly at family gatherings and weddings. They are not grounds for choosing a partner. If the profile fits you, a gentler lesson may be this: steady affection is valuable, and saying it out loud now and then helps others see it.
Frequently asked questions
Is the Vietnamese zodiac sign an Ox or a Buffalo?
A buffalo. Vietnamese tradition uses con Trâu, the water buffalo, for the Sửu branch, reflecting its central place in rice farming. English writing usually keeps the Chinese “Ox”, and both refer to the same position in the cycle.
I was born in January 1997. Am I an Ox?
If you were born in early January, no: you belong to the Rat year that began in 1996. For a late January or February birthday, check the 1997 Tet date on a Vietnamese lunar calendar.
When is the next Ox year?
The next Ox year begins at Tet 2033. It will be a Water Ox (Quý Sửu) year, the first of that pairing since 1973.
What is the difference between “Earth Ox” and the Ox’s Earth element?
The Sửu branch always belongs to Earth. “Earth Ox” refers to the year’s stem element, which changes. An Earth Ox year, such as 1949 or 2009, is simply one where both point to Earth.
Which signs are traditionally linked with the Ox?
Folklore groups the Ox with the Snake and Rooster, pairs it with the Rat, and sets it opposite the Goat. Treat these as cultural tradition rather than relationship advice.
