This stamp is from 1991 Chinese Traditional Gods issue showing Fu star,namely God of Good Fortune.
Fu Lu Shou (simplified Chinese: 福禄寿; traditional Chinese: 福祿壽; pinyin: Fú Lù Shòu) refers to the concept of Good Fortune (Fu), Prosperity (Lu), and Longevity (Shou). This Taoist concept is thought to date back to the Ming Dynasty, when the Fu Star, Lu Star and Shou Star were considered to be personified deities of these attributes respectively. The term is commonly used in Chinese culture to denote the three attributes of a good life.
The Fu star (福) refers to the planet Jupiter. In traditional astrology, the planet Jupiter was believed to be auspicious. Alternately, according to Taoist legend, the Fu Star is associated with Yang Cheng, a governor of Daozhou. Yang Cheng risked his life by writing a memorial to the emperor to save the people from suffering. After his death, the people built a temple to commemorate him, and over time he came to be considered the personification of good fortune.
He is generally depicted in scholar's dress, holding a scroll, on which is sometimes written the character "Fu". He may also be seen holding a child, or surrounded by children.
