The Ly line (Vietnamese: chi Ly; chữ Hán: 支離; chi can also be translated to as branch) was the sixth dynasty of Hùng kings of the Hồng Bàng period of Văn Lang (now Viet Nam).

Starting 1712 B.C., the line refers to the rule of Pháp Hải Lang and his successors, when the seat of government was centered at Phú Thọ.

A new dawn of Vietnamese civilization during the Bronze Age in the Red River delta emerged approximately 1700 B.C.

During early time, a deceased person was usually buried with many pieces of pottery, axes, chisels and utensils such as vases and bowls.
