:{{see also|Chinese siege weapons}}
The earliest documented occurrence of ancient siege-artillery pieces in China was the levered principled traction catapult and an {{convert|8|ft|m|abbr=on}} high siege crossbow from the [[Mozi]] (Mo Jing), a Mohist text written at about the 4th – 3rd century BC by followers of Mozi who founded the [[Mohism|Mohist school]] of thought during the late [[Spring and Autumn period]] and the early [[Warring States period]]. Much of what we now know of the siege technology of the time comes from Books 14 and 15 (Chapters 52 to 71) on Siege Warfare from the Mo Jing. Recorded and preserved on bamboo strips, much of the text is now extremely corrupted. However, despite the heavy fragmentation, Mohist diligence and attention to details which set Mo Jing apart from other works ensured that the highly descriptive details of the workings of mechanical devices like Cloud Ladders, Rotating Arcuballistas and Levered Catapults, records of siege techniques and usage of siege weaponry can still be found today.<ref>Liang, Jieming (2006).
