The Zhang family in the west of Wuzhuang Village, Liqiao Town has lived in Shunyi for more than 350 years. Since arriving here, the family has always insisted on recording the "family tree". The changes of each generation of the family are recorded in detail, preserved, and the family tree is determined by the elders of the family. While recording the family tree, each branch follows the family rules and holds the "Qingming Meeting" regularly. During the annual festivals, each family looks for the ancestor and presents the family tree and holds sacrifices. The elders also educate the next generation on ancestral teachings, which has never stopped, and the book is compiled into the "Zhang Family Genealogy". The family tree records that have been passed down for hundreds of years are aimed at not losing the true heritage of the family history, so as to serve as a warning and punishment for the same clan members, eliminate the bad habits of resentment, and create a friendly impression.
