Starting in June, if you do not have a reusable cup with you, you will have to pay extra to have your drink in a plastic or paper cup. In order to reduce plastic and paper waste, Korea is implementing a cup deposit, where you pay ₩200-500 ($0.17-0.42) if you don’t have a reusable cup. You get the money back when you return the paper or the plastic cup from the store you got it from and they will properly recycle it.

몇년생이에요? (myeoch-nyeon-saeng-i-e-yo, “What year are you born?”). Because Korea has their own age system when everyone turns a year older on January 1st, people ask what year you are born, rather than how old you are.

If you have been to Korean, Chinese and Japanese restaurants, you may have noticed that the chopstick sizes are different and from the three countries only Koreans traditionally use a spoon to eat rice. And among the three countries Korean utensils are metal. Because silver changes color when exposed to toxins, Korean royals used silver spoons and chopsticks to detect poison in their food. This practice became a trend for commoners and using metal utensils became a thing. When eating rice, unlike Japanese, Koreans do not pick up the bowl so the long length helps with movement.

Starting this month [June, 2021] Korean male celebrities cannot go to the military when they’re under investigation. This is one the most common tactics we’ve seen from male celebrities whenever there’s some kind of controversy or investigation, you often see them just going to the military. By doing this, it makes it harder for the investigation to proceed and most importantly, you’re out of the public's attention for 2 years and most of the time people just forget.

The Gu Hara Act prevents parents from inheriting their children’s assets when they didn’t even fulfill their parental duties. Gu Hara’s mother abandoned her and her brother when they were very little. She wasn’t present in Hara’s life until she died in November 2019. She showed up to the funeral and demanded 50 percent of Hara’s assets [typically 50 percent went to the mother and father each]. Unfortunately, this act doesn’t apply to Hara [as it was passed in 2021] and 40 percent was given to the mother [the rest was given to the father who gave his share to Gu Hara’s brother]. But the rest of the money will be used to help single parents and struggling trainees.

As there are many different funeral customs around the world, some countries have very festive funerals where people wear bright colors and the overall atmosphere is positive to celebrate the life the person lived. But the funeral customs in Korea are dark and sad and nothing near celebrating. It is common etiquette to show up to a Korean funeral wearingblack. Darker clothing is okay, but if you wear bright colors, it will be a bad impression.

If you whistle at night, an adult will say something like 휘파람 불자마 (hwi-pa-lam bul-ja-ma, ‘Don’t whistle’!). If you whistle at night, you’re gonna call the ghosts out.

One of the craziest days in Korea is 수능 (su-neung) testing day which is kind of the same things as an SAT in America. However, unlike in America where the SAT which can be taken multiple times, Koreans get one shot at the exam. So if they don’t do well they have to wait until the next year to take the exam. It’s a day that they have been preparing for their entire lives which also explains why the suicide rates soar this time of year. On this day, businesses open late, highschools close, people are encouraged to stay off the roads to help students get to the testing site.

Here are some crazy things that happen on this day. If you forget your student ID, a police car will go get it for you.

Miyeok guk (미역국) is strictly prohibited because it will cause the answers to slip out of their head. Sticky candy is a yes because it will help you stick to the university you want to get into.

Bringing tofu to prison. It’s not the cooked tofu. When you’re on your way to pick up a friend or family member from prison, you bring a chuck of tofu with you and then the person released from prison takes a big bite of the tofu. Because the tofu is pearly white, it’s a symbol of cleansing the soul and a new beginning. By eating the tofu, the convict resolves to living a crime-free life moving forward.

Throwing salt in the vicinity of someone who left bad energy. Back in the day, a lot of Koreans believed in spirits and ghosts. They believed the root cause of illnesses and just bad things rooted from bad spirits. So say that a Karen walks into your restaurant and you don’t want her negative energy to stay in your restaurant. You just throw salt at the entrance where she walked out.

Never write someone’s name in red ink because it symbolizes death.

Number 4 is unlucky because it symbolizes death. Fun fact: since number 4 is unlucky in Korea a lot of people refuse to live on the fourth floor which is why a lot of the time fourth floor rooms are a lot cheaper.

Do not place a mirror in front of the front door because it reflects all of the good luck that tries to come in inside your house.

Do not gift shoes to your significant other because it will cause them to run away from you.

A lot of times when Korean celebrities are exposed for bad behavior, international fans say things like “who cares, if they’re good at their job, that’s all that matters.” However, that is not the case in Korea. Even in the show Produce 101 they spilled coke on the ground to see if the girls will do anything off camera. Among the girls who acted like they didn’t see anything because it wasn’t their mess, Kim Se-Jeong cleaned up everything and became more popular.

Not saying ‘bless you’ when someone sneezes. Some people say we say ‘bless you’ because when we sneeze our soul leaves our body and ‘bless you’ is used as protection from the Devil, but in Korea it’s not a thing.
 
Girls holding hands. In Korea it is very common to see girls holding hands with each other and walking with their arms locked to each other. It just means their besties.
 
Seeing no color in the streets during the winter time. Long black puffer. So I need to say more? Everyone wears them. It’s definitely one of those things where you didn’t know you needed it until you got it.

South Korea is a safe country with low crime rates but of course, when it gets late at night, you do have to be careful.

The Korean entertainment industry has been flooded by bullying allegations recently and here are some things you should know. A lot of international fans argue that everyone gets bullied in school and it’s not that big of a deal.

But here are some main differences between bullying in America and bullying in Korea. To start off, in English there is the term ‘bullying’, but in Korea they just use the acronym for 학교 (hak-kio, ‘school’) and 폭력/폭행 (pog-lyeog/pog-haeng, ‘violence’) and say 학폭 (hak-pok). The fact that the term ‘violence’ is used to describe bullying, you kind of really know how serious it is. Bullying in Korean schools isn’t really stealing someone's lunch money or calling someone a mean name. The act of bullying in Korea is literally wanting to prove superiority by completely degrading someone’s dignity. The bullying you see in k-dramas happens in real life.

Mouth tail that’s raised upwards - gives off a “softer” look even when you’re not smiling.

Besides toilet paper and cleaning supplies being something everyone can never have too much of, cleaning supplies bring good luck and fortune to the person who moves into the new home.

You probably already know that Korean students wear uniforms, but you probably don’t know how strict they are when it comes to not just dress code but physical appearance. Throughout the years the rules have become more lenient but at one point all female students had to have the same hair length. You weren;t allowed to wear makeup, you weren’t allowed to have piercings and you know kids are on break when they bleach their hair. Recently they went after schools in Seoul that had dress codes talking about bras, stockings and socks. Because the school uniform shirt is white, the dress code states that you have to wear a white or a skin-tone bra. Not quite sure if it’s gonna make a crazy difference but at least they can’t call you out for it.

About a decade ago, the most common household was comprised of 4 people, but now that number is 1. The marriage rate and birth rate hit all-time lows and the number of people living alone is continuing to skyrocket. To accommodate this big group of people living alone starting in November [2021] Seoul city is rolling out the door-to-door service. One of the biggest downsides to living alone is that you’re kinda left alone during times of emergency or when you have to go to the hospital. The door-to-door service allows someone to come to your house to escort you to the hospital and just become your helping hand. The service rate has been set to ₩5,000 ($4,25) an hour and the service is expected to be especially helpful for the elders living alone. But there are some mixed responses. While there are positive ones, there are also safety concerns.

From ages 18 to 28, if you are a healthy Korean man, you have to serve in the military for a little bit less than 2 years.

The first reason is kind of obvious. South Korea is still at war. We’re only a couple of weeks into 2022 and North Korea fired its fourth missile test. And unlike in other countries like the US, a lot of Koreans do not voluntarily join the military. So without conscription it is impossible to have enough military in case something were to happen.

There are times when healthy Korean men can get military exemption like soccer player Son Heung-Min who won a gold medal for South Korea at the 2018 Asian games.

The phrase 잘먹었습니다 (jal-meog-eoss-seub-nid-a) which is said after eating, meaning “I ate well.” Or 잘먹겠습니다 (jal-meog-gess-seub-ni-da) which is said before eating, meaning “I’ll eat well.”
