In order to publicize China's elegant arts and the finest traditional customs of the Chinese people, a set of 〝Chinese Folklore Postage Stamps (Issue of 1975)〞 was released. The designs feature respectively an acrobat who exhibits skill with an iron rod with a fork on both ends and two acrobats who use a string wrapped around the spindle of a carved bamboo top and whirl it with their hands, causing the top to make a constant buzzing sound.
