Hsu Chiu-chi, who once sold stamps on the roadside on Kuling Street, notes that many high school students go there to buy stamps, and talk prices by the package (each package includes 200 sheets, with a small complete sheet being one whole set and a large complete sheet made up of a number of these sets).
