Before making the timeline of historical dynasties, the time nodes (intervals) corresponding to historical dynasties can be sorted out first. For example, we simply sort out the development order of historical dynasties as follows:

Xia dynasty->; Shang dynasty->; Western Zhou dynasty->; Spring and Autumn Period and Warring States Period->; The Qin dynasty->; Han dynasty->; The three kingdoms, Jin dynasty, southern and northern dynasties->; Sui dynasty->; Tang dynasty->; Five Dynasties and Ten Countries-> Northern song dynasty->; Southern song dynasty->; Yuan dynasty->; The Ming dynasty->; Qing dynasty.
