1? Special stamps have different requirements for special stamps and stamps of different ages: Group A should use more stamps, accounting for about 50%, and use stamps and films that have been used by postal services to display hard-to-get stamp products; Group B should use more stamps such as envelopes, with special topics and stamp products descriptions, and require the postage of stamps such as envelopes to be correct, and use "hard-to-collect" stamps to show important stamp collecting characteristics; Group c requires the use of various philatelic products, accounting for more than 30% ~ 40%, and rare philatelic products (samples, printed matter, variants, etc.). ) should be chosen, depending on the difficulty of obtaining them. In selecting materials, we should avoid using stamp products that are not too expensive in appearance, don't mix new tickets with old ones, don't show the cover of a small promissory note alone, and don't stick a full set of stamps. The explanatory text of the special topic should be accurate and consistent with the displayed philatelic products.
2? For traditional stamp collecting, the "plan" should be as logical as mathematical reasoning, and be detailed and clear step by step. Its "title" and "plan" should be put on one page and should not be separated. In displaying knowledge, you can take notes without topics. A brief description of postage, postal route and the start and end time of stamp use can show your knowledge and research level, but it is not necessary.
3? For stamp products, there are three ways to choose: one is the stamp products of a country for a period of time; The second is a set of postal supplies of a certain country; Third, postal supplies issued by many countries for the same purpose. All three kinds of stamps should follow their own main lines. The material of stamp products is seal, and the used old stamp products have higher evaluation than the new ones that have not been sent. When arranging, avoid that each poster is two cover pages aligned up and down, which is dull due to lack of change.
