This is how you usually go to Anton.
Take the light rail at the airport, go to Sassansa (the terminal of the light rail), then take the No.2 subway to Semian West Station, and change there to 1 subway to the terminal no po old shop. Here, Busan bus station. Here, find a bus ticket agency outside the city, and you will get a direct ticket to Anton.
There is a Chinese broadcast in the subway station. I wrote the Korean pronunciation of Pinyin.
