The gun license is renewed every two years. The exchange should be completed one month before the expired date (before December). Each management organization ought to prepare two copies of inventories for license renewing in terms of guns in type A and B (see the attached file) and two two-inch, hat-off, half-length portraits of license owner along with the original pictures of gun to be examined to the examination organization. (Note: See page 6216 in Compendium of Current Laws and Regulations in the Republic of China, May, 1994 for the attached files.)
