It is ten years that I began to show interest in collecting stamps. Now my collection of stamp covers almost every category, Chinese zodiacs, place of interest and historical people and events including. Believe it or not, from these small stamps I have learned much about which I can't get from textbooks. Meanwhile, I have made friends with those with same hobby, with whom I constant share my opinions and feelings so long as I've got a value new stamp.

Collecting stamps is a fun and of course has greatly changed my life, bringing many advantages to my study so well as to my life.
