Apart from postage stamps, one can also collect:
I. First Day Covers First day covers are special envelopes accompanying the release of new stamps. The front side bears a cachet (design and text corresponding to the theme of the stamps) as well as the new stamp release, which is tied by a cancellation showing the issue date of the new release.

II. Folders with or without Crystal Mounts Each new stamp release comes with folders with or without crystal mounts. The folder with a crystal mount has a protective clear crystal mount to hold the stamps, and the folder is varnished. The folder without a crystal mount is not varnished, so the stamps can be cancelled.

III. Addressed Covers An addressed cover is an envelope or postal card bearing stamps or postal indicia that was sent through the mail by the postal authorities.

IV. Thematic Stamps Thematic stamps are collections of stamps grouped by their images or by the purpose of their releases, such as stamps on flowers, fish, the Olympics, etc.

V. Souvenir Sheets A souvenir sheet is a full set of stamps or a single stamp or several stamps from a set printed on a small sheet of paper.

VI. Postal cards 1. It is a piece of stiff paper used for correspondence.
2. It cannot be sealed
3. According to Chunghwa Post′s regulations, a postal card must be smaller than 14.8 × 10.5 cm, and larger than 14 × 9 cm. A variance of 0.2 cm from these standards is allowed.

VII. Letter Sheets A letter sheet is a sheet of paper that can be folded into an envelope, sealed and mailed. It could be described as a letter and envelope in one. The outside bears either an indicium or a postage stamp, whereas the inside provides a space for correspondence.

VIII. Postmarks 1. Postal markings are cancels or postmarks that indicate the time and place of a mail being processed. Most postmarks are circular in shape with a diameter under 3 cm and show the name of the post office of origin and the processing date and time.
2. Postmarks are very important data for the research of postal history. When conducting a philatelic monographic study, having clear legible marking to use as evidence is especially important.
3. When doing textual research into a stamp′s origin and period of use, one can refer to the dates and places shown on postmarks and cancellations. The joy and value found in the postmarks can often exceed the value found in the stamps themselves. Therefore, it is very important to preserve the original covers.

IX. Philatelic Items You can collect anything related to philately, including postage stamps, envelopes, postal cards, letter sheets, stamp pictorials, stamp folios, postmarks, parcel post stamps and materials released by the postal authorities.
