Wen 8 stamps have two colors, one is gold and the other is red.

Among the Wen 8 stamps, two stamps, the famous building in China and the famous library in China, are hot-stamped, and their color code is gold. This printing method makes these two stamps more beautiful visually and more collectible.

All the other stamps in Wen 8 stamps are lithographically printed, and their color code is red. Although this printing method is not as beautiful as bronzing printing, it still has certain collection value.
