Busan has to tread on the beach by the sea. The beach is quite soft. Looking at the golden coast, of course, you have to roll up your trousers, take off your shoes and socks and go straight into the waves. God! This sea water is too cold, from the bottom of my feet directly into the top of my head, let me shiver! Within a minute, you can only go back to the sand and soak your feet in the warm sand. But... After all, the addiction is over, willing to leave the foraging.~
