I'll tell you a place, just on the 25th floor of Dalian World Trade Center, where there is a "Korea Exchange Bank" specializing in the business you mentioned, haha! I work in the lobby opposite them. I'll tell you the specific address, 25th floor, World Trade Center, No.25 Tongxing Street, Zhongshan District, Dalian (behind Friendship Mall, which is the tallest building in Dalian at present). Take elevators 4, 5 and 6, and go out on the right. They rest at noon 12 and go to work in the afternoon 1. How about details?
