As I didn't know about the laws about drinking in Korea, I researched it before. = I had recently researched it. However, It's hard to find the laws for alcohol. Therefore, I'll write down with my experience and knowledge about alcohol. At first, we didn't have restrict = any restrictions on time to buy and drink alcohol. We can buy and drink alcohol anytime when we want. Also, if restaurant have a permission to sell alcohol, they can sell it. I know that we could not drink alcohol outside but policeman = policemen regulate so softly that we can drink on the road easily. I think we only have restriction on age to drink alcohol. They can do anything if it is related on alcohol. Only they can do when they become twenty. If restaurants and convenience = convenient stores sell alcohol to below twenty person = persons below twenty, they were stopped selling their stuffs by the law. = they will be banned from selling their stuffs by law.  Therefore, the restriction on age is regulated strictly.
