10 Things You Should Never Do in Korea｜Avoid These Cultural Mistakes

Korea is a friendly and welcoming country, but like any culture, there are unspoken rules that may surprise visitors. Knowing what not to do is just as important as learning polite phrases.

Here are 10 things you should never do in Korea to avoid awkward situations and show cultural respect.

1. Don’t Stick Your Chopsticks Upright in Rice

This resembles a ritual performed at funerals and is considered extremely bad luck. Always lay your chopsticks on the side of your plate instead.

---

2. Don’t Blow Your Nose at the Table

In many Western countries it’s acceptable, but in Korea it’s seen as rude and unappetizing. If you need to blow your nose, step outside or go to the restroom.

---

3. Don’t Speak Loudly on Public Transport

Korean buses and subways are usually very quiet. Loud conversations or phone calls may bother others and draw unwanted looks.

---

4. Don’t Give or Receive with One Hand Only

When handing something to someone—money, a drink, a business card—use two hands or support your right wrist with your left hand. This shows respect.

---

5. Don’t Put Your Feet on Seats

Whether on the subway, bus, or in public areas, putting your feet up is considered disrespectful and unhygienic.

---

6. Don’t Write Names in Red Ink

Traditionally, red ink was used to write the names of the deceased. Many Koreans still consider it bad luck or inappropriate.

---

7. Don’t Refuse a Drink Too Abruptly

Korean social culture values harmony. If someone offers you a drink, rejecting it too bluntly may feel rude.

You can simply say: “천천히 마실게요” (I’ll drink slowly) or accept lightly.

8. Don’t Start Eating Before Older People

Korean dining culture emphasizes respect for age. Wait until the oldest person at the table lifts their spoon before you begin eating.

---

9. Don’t Touch Someone’s Shoulder or Back Casually

Friendly touching is common in some cultures, but in Korea, physical contact with strangers or acquaintances is more limited.

---

10. Don’t Wear Shoes Inside Someone’s Home

Korean homes are shoe-free spaces. Always take your shoes off at the entrance unless the host clearly says otherwise.

Final Thoughts: Respect Goes a Long Way

Koreans are understanding and welcoming toward foreigners, so don't stress too much. However, knowing these cultural boundaries shows respect and will help you blend in smoothly.
