Socialising Etiquette
In Korea, it's polite to avoid close physical contact, but it's also appropriate to respect others' personal space. This means that you shouldn't approach people too closely, wave your arms about close to them, or otherwise move your body in a way that might make people feel uneasy.
For instance, if you're mingling with Korean friends, try not to constantly touch or wave your arms in front of them. In general, Koreans wouldn't do it unless they were very close to the other person because it may make them look bad. Invading someone's personal space violates traditional Korean societal norms, which will be discussed in greater detail later, and can lead to awkward situations as well as embarrassment for the one in question.
In a society where hierarchy is so crucial and individualism is covertly frowned upon, respect is essential to establishing and preserving harmony. There are three appropriate methods to behave with deference in Korea, including proper handshakes, bowing, and gift-giving. There are established guidelines that must be observed in every situation to prevent disrespect. Learning these three basic forms of respect will show that you are aware of Korean cultural norms and will make it easier for you to integrate into Korean culture.
