Behind the railway station, on the first floor of the sixth floor of Koreatown, there is a new building in the big food market, selling office supplies. The two kinds of paper you mentioned are sold in many stalls, and they are cheaper than those outside. If you go to the typing and copying agency to print your business card, he will generally recommend you an expensive business card, saying it is Daming paper, which is of good quality. Then one day I took a bus and saw the brand of Daming Paper. On Tongshan Street next to Tangshan Street Children's Hospital, you can also go there and ask if it is cheaper than the business card paper in the market.
