Bai Zi Chong, also known as Bai Zi Lian Zhu Pao (百子連珠砲, lit. 'Hundred bullet rapid fire cannon'), is the Chinese name for muzzle-loading swivel gun. It is similar to its breech-loading counterpart in most respect. Prized for its wide arc of fire and accuracy, Bai Zi Chong is used primarily as shipborne anti-personnel ordnance and siege defence.

Shou Shang Bai Zi Chong is a particularly lightweight variant of Bai Zi Chong that only requires one gunner to use, and presumably can be fired handheld. Despite its name, it is usually mounted on war carts such as Qing Che (輕車) and Jia Huo Zhan Che (架火戰車).
