A legendary long-lived figure in China. He supposedly lived over 800 years in the Yin Dynasty (?? 1900 to 1066 BC). Some legends say that one year was 60 days in ancient China; that made him more than 130 years old. Others say he was over 200 years old or over 400 years old. Another says he was accidentally left off of the death list in heaven. Peng Zu was regarded as a saint in Taoism. The pursuit of eternity drugs by supporters of Taoism was highly influenced by Peng Zu. He is well known in Chinese culture as a symbol for long life, nutrition treatments, and sex therapy treatments. Legend maintains he married more than 100 wives and fathered hundreds of children, as late as in his 800s.
