If you happen to be fortunate enough to get invited to someone’s house, don’t forget to take off your shoes. This goes as well for visiting temples. Koreans maintain the cleanliness of these places and it would be very disrespectful to wear something dirty inside. As a practice, people have slippers that are used just inside the house to avoid walking barefooted.
