"Shi xi" or "family pedigree" is a list of the relationship between members of a family as well as events happened in the family. And the lineage illustrated in the form of a chart is called "a shi xi biao" or "a pedigree chart". In the chart, the closeness, origin, procreation and marriages of all family members are documented in detail from the first ancestor to the date of the chart editing. The keeping of a pedigree chart reflects the traditional Chinese family view.
