The '''Chấn line''' ({{langx|vi|chi Chấn}}; [[chữ Hán]]: 支震; ''chi'' can also be translated to as ''branch'') was the fourth dynasty of [[Hùng king]]s of the [[Hồng Bàng]] period of [[Văn Lang]] (now [[Vietnam]]). Starting 2252 B.C., the line refers to the rule of Bửu Lang and his successors, when the seat of government was centered at [[Phú Thọ Province|Phú Thọ]].<ref>Nguyễn Khắc Thuần 2008, pp. 14–15.</ref>

==History==
Bửu Lang{{refn|group=lower-alpha|Another name is "Bảo Lang".}} (year of birth unknown) took the [[regnal name]] of '''Hùng Diệp Vương''' (雄曄王){{refn|group=lower-alpha|Another spellings for the name are "Hùng Việp Vương" and "Hùng Hoa Vương".}} upon becoming Hùng king.<ref name="bietlam">Biệt Lam Trần Huy Bá. (article title unknown). ''Nguồn Sáng'' magazine ''23'' - 1998.</ref> The series of all Hùng kings following Bửu Lang took that same regnal name of Hùng Diệp Vương to rule over Văn Lang until approximately 1913 B.C.<ref name="bietlam" />

The burial customs of this period were that the bodies lay straight. But a sick deceased was usually laid to rest curled in the fetal position.<ref>[https://www.nytimes.com/2012/12/18/science/ancient-bones-that-tell-a-story-of-compassion.html?_r=3& Ancient Bones That Tell a Story of Compassion.] Retrieved 2014-01-02.</ref>

The evidence for early [[Vietnamese calendar]] system was recorded on stone tools dating back 2200–2000 BC. Parallel lines were carved on the stone tools as a counting instrument involving the [[lunar calendar]].<ref>[http://english.vietnamnet.vn/fms/art-entertainment/48893/ancient-calendar-unearthed.html Ancient calendar unearthed] {{Webarchive|url=https://web.archive.org/web/20140103230439/http://english.vietnamnet.vn/fms/art-entertainment/48893/ancient-calendar-unearthed.html |date=2014-01-03 }}.

Sometimes around 2000 B.C., the [[Phùng Nguyên culture]] arose and lasted about 1000 years.<ref name="bakhoach">Nguyen Ba Khoach 1978</ref> At the end of its time, it must have overlapped with the cultures of the later period.<ref name="bakhoach" />

Also during this time, population from the mountainous areas moved out and began to settle in the open along the rivers to join the agricultural activities.<ref name="bakhoach" /> The [[slash-and-burn]] method was introduced to create fields.<ref name="bakhoach" /> In addition, the population started to raise their own animals.<ref name="bakhoach" /> Archaeologists had discovered the remains of domesticated animals.<ref name="bakhoach" />
