If I visit a person's home in Korea what should I do?

First, when a visitor enters the house he/she should bow politely and give the person food to eat.
Also, when talking to the other party you should make a good impression and speak politely.
Likewise, do not touch or use the homeowner's stuff.
Also, do not go into the other room without asking for permission.
Then, do not cry loudly and do not jump. After using the toilet, make sure that you will leave it clean and tidy.
Finally, do not desecrate the house of the owner.
