“The stamp is the necessary code that allows people to exchange their feelings and private information in their daily lives. Choosing different national flags as stamps provides the visual meaning of international communication, and also symbolizes the possibility of visual participation in democracy. Beginning with the form of the national flag itself is the best way of presenting the citizen with the most simple icon, and as well as the most abstracted symbol. The symbol can refer to visual art itself, as seen in Kandinsky, Mondrian, Malevich, and Reinhard. The numbers are symbols of equality, and all languages lack universal justice compared to these numbers. “2000〃 means the beginning of the new millennium, and indicates peoples’ expectation as well as new possibilities at the end of the 20th century.” – Ren Jian (about his panting.Stamp Collection, 1991, Acrylic on canvas).
