Monkey stamps, also known as Gengshen monkeys or golden monkeys, are a set of zodiac stamps issued by the former Ministry of Posts and Telecommunications (referred to as China People's Post) on February 15, 1980 (the Gengshen year). The monkey stamp is the first zodiac stamp issued by the Republic of China. China Philatelic Corporation issued a first-day cover at the same time as Monkey Ticket. Historically, every price change of monkey tickets was accompanied by changes in the postal market.
