Real-World Social Etiquette in South Korea: A Guide for New Teachers

Plunging into a new country as an ESL teacher is exciting, but adjusting to a fresh social landscape can trigger a fair bit of culture shock. South Korea is a deeply polite, collectivist society where social harmony, hierarchy, and mutual respect dictate everyday interactions.

While locals generously grant foreigners a “grace period” for minor cultural slip-ups, picking up standard social norms quickly builds goodwill with co-teachers, hagwon directors, parents, and your young students.

Here is the essential guide to Korean social etiquette—including the small quirks and classroom rules—written to keep your transition smooth.

1. The Red Ink Rule and Classroom Superstitions

When you start grading homework or writing examples on the whiteboard, keep one major rule in mind: never write a living person’s name in red ink.

Historically, names of the deceased were written in red on funeral banners and registry records to ward off evil spirits. Writing a living person’s name in red carries an unlucky connotation, almost like wishing bad luck or death upon them.

In the Classroom: If you are marking attendance, returning test papers, or writing a student’s name on the board to award points, always stick to black, blue, or green ink. Kids will immediately gasp or point it out if you pick up a red marker by mistake.
Number 4: Be aware that the number four (sa) sounds identical to the Chinese character for death. You might notice elevators skipping floor 4 or labeling it as “F.” Avoid grouping kids into groups of four or handing out work items in sets of four when you can help it.

2. Working with Kids and Handling Physical Contact

Teaching young learners in Korea requires a delicate balance of warmth and boundaries. While elementary and kindergarten students can be very affectionate, how you interact with them physically matters.

Patting Heads: In many Western countries, a quick pat on the head is a natural way to praise a child. In Korea, touching someone’s head—even a child’s—can be seen as overly condescending or inappropriate, as the head is traditionally considered the most sacred part of the body. Stick to high-fives, thumbs-ups, or gentle shoulder pats for praise.
Beckoning Students: When you call a student to come up to your desk or join a group, never palm-up beckon with a single finger. Curling your index finger with your palm up is how people call pets in Korea and is considered disrespectful when used on humans. Instead, extend your hand with your palm facing down and gently wave your fingers toward yourself.
Addressing Students: Korean names usually consist of a one-syllable family name followed by a two-syllable given name. When addressing young students, attaching -ah (if the name ends in a consonant) or -ya (if it ends in a vowel) to their given name is a natural, affectionate way locals speak to children. However, in the classroom, using their preferred English name or full Korean name works perfectly.

3. The Golden Rule: The Two-Handed Pass

If you remember only one physical habit during your time in Korea, make it this one: always give and receive items using both hands.

Whether you are paying for groceries at GS25, handing back a graded test to a student, accepting a cup of coffee from a co-teacher, or passing a business card to your director, use two hands. If one hand is occupied, extend the item with your right hand while lightly resting your left hand on your right wrist or forearm.

Using a single hand to pass something over—especially to someone older or higher in status—can come across as dismissive or sloppy. Teaching your young students to hand papers back to you with two hands is also a great way to build mutual classroom respect.

4. Navigating Age, Hierarchy, and Titles

In Western cultures, asking someone’s age right after meeting can feel overly personal. In Korea, it is standard procedure. Korean grammar and social interactions rely heavily on age and seniority, which determines honorific speech levels, who sits first, who drinks first, and how titles are used.

If a colleague or new acquaintance asks your birth year right away, they aren’t judging you; they are establishing where you both fit in the social hierarchy so they can address you respectfully.

Avoid addressing Korean colleagues or administrative staff solely by their first name unless explicitly invited to do so. A safe baseline is using their last name followed by their professional title and the honorific suffix nim—such as Kim Seonsaeng-nim (Teacher Kim) or Director-nim.

5. Table Manners and Eating Around Colleagues

Meals in Korea are communal, vibrant, and fun, but the Korean dining table comes with a few specific ground rules:

Wait for the Eldest to Start: At staff dinners (hoeshik) or shared lunches, do not dig into your food or take a sip of your drink until the eldest person at the table picks up their spoon or chopsticks first.
Chopstick Placement: Never stick your chopsticks upright into a bowl of rice. This mirrors incense burned at traditional funeral rites and is considered deeply unlucky. Rest them on a chopstick holder or flat across the side of your dish.
Blowing Your Nose: Avoid blowing your nose at the dinner table. It is considered unhygienic and unpleasant for those around you. Quietly excuse yourself to the restroom instead.

6. Drinking Culture Etiquette

After-work dinners or weekend drinks with co-workers are central to building team cohesion. When sharing drinks, keep these gestures in mind:

Never Pour Your Own Drink: Pour for others around you when their glasses are empty or low, and wait for someone else to refill yours.
Pour and Receive with Two Hands: Hold the bottle with both hands when pouring for a colleague, and hold your glass with two hands when receiving a drink.
The Turn-Away Sip: If an older colleague or manager toasts with you, turn your head and body slightly away from them when taking a sip out of respect.
Declining Alcohol: If you don’t drink, simply accept the first glass offered out of politeness, set it down, and refill your glass with water, soda, or tea for subsequent toasts. Nobody will force you to drink alcohol if you politely decline, but participating in the toast keeps the harmony intact.

7. Personal Space, Shoes, and Public Manners

Shoes Off Indoors: Always remove your shoes when entering someone’s home, a traditional restaurant, and even certain hagwons or school play areas. Look for a lowered entryway (hyeon-gwan) where outdoor shoes are left, and step into the provided house slippers. Keep clean, presentable socks on at all times.
Public Transit Volume: Keeping your voice down on subways and buses is standard practice. Loud phone calls or rowdy conversations draw disapproving looks, especially from older commuters.
Sneezing and Coughing: Always cover your mouth with your inner elbow rather than your hands when coughing or sneezing, particularly around young children and in crowded school hallways. Wearing a mask when you have a mild cold is expected and appreciated by parents and fellow teachers alike.

Showing that you care about these small cultural nuances goes a long way. Locals and co-teachers will notice the effort immediately, making your time teaching in Korea all the more rewarding and smooth!
