What cultural faux pas should I try to avoid making in Geoje?

"When visiting Geoje, it's important to respect the local customs and traditions to avoid any cultural faux pas. Avoid using one hand when giving or receiving items, as it's considered rude. Always use both hands or your right hand with your left hand supporting your right wrist. Avoid pointing with your fingers, as it's considered impolite. Instead, use your whole hand to gesture. In Korea, it's considered disrespectful to write a person's name in red ink, as it symbolizes death. When dining, wait for the eldest person to start eating before you begin. It's also considered impolite to leave the table before the eldest person has finished eating. Avoid blowing your nose in public, as it's considered rude. In Korea, shoes are usually removed before entering homes, some traditional restaurants, and other places with tatami or wooden floors. Avoid touching, hugging, or making physical contact with people you are not close with, as Koreans value personal space. It's also important to avoid discussing sensitive topics such as politics, North Korea, and the Korean War. Lastly, remember to bow when greeting someone. The depth of your bow indicates the level of respect you have for the person you are greeting," said another expat in Geoje, Korea.
