How old did Peng Zu, Jiang Ziya, Guiguzi and Chen Tuan live?

According to legend, he lived 880 years, which was the age referred to by the method of taking 66 days as a year at that time. At present, he takes 365 days as a year, and his actual life expectancy is 120 years. According to historical legend, Peng Zushou is 880 years old, which is the result of the "small flower counting method" in Pengshan area in ancient times. The counting method of floret comes from "60th birthday", which is the time when sixty stars were on duty one by one in ancient times. Folk worship the stars in the sky, and the life span of mortals corresponds to the stars, so 60 stars are needed to be on duty in turn every year. According to this calculation, the actual life expectancy of Peng Zu today is 159 years.
