Fo Lang Ji (佛狼機, lit. 'Frankish engine'), named after the Chinese term for Portuguese people, is the Chinese version of the breech-loading swivel gun, which they reverse-engineered from the Portuguese berço around 1510 AD. Fo Lang Ji quickly supplants Chinese-made cannons as the most important artillery piece in the Ming arsenal.
The Chinese created many variant designs of the Fo Lang Ji based on the basic Portuguese model.

There are many specialised version of the Fo Lang Ji, such as the Ma Shang Fo Lang Ji (馬上佛狼機, lit. 'Horseman's Frankish engine') designed to be used on horseback, Bai Chu Xian Feng Pao (百出先鋒砲, lit. 'Hundred discharge vanguard cannon') a small Fo Lang Ji with shortened barrel and an attached blade, double-barreled Lian Zhu Fo Lang Ji Pao (連珠佛朗機砲, lit. 'Rapid fire Frankish engine'), triple-barreled Liu Xing Pao (流星砲, lit. 'Meteor cannon'), etc.

Wu Di Da Jiang Jun is the heaviest field artillery in the Ming arsenal until the adoption of Hong Yi Pao (紅夷砲). It weights one thousand and fifty catties. Each of its three chambers is loaded with one large stone ball and five hundred small iron shots.
Wu Di Da Jiang Jun is heavy and ponderous, and has relatively short range despite its size, and has to be mounted on a heavy cart to have any mobility at all. This means battlefield maneuvering and adjusting muzzle elevation is all but impossible for this weapon.
The disadvantages of Wu Di Da Jiang Jun eventually lead to the development of Ye Gong Shen Chong (葉公神銃).
Wu Di Shen Fei Pao (無敵神飛砲, lit. 'Invincible divine flying cannon')

Like its land-bound counterpart, Wu Di Shen Fei Pao is the heaviest naval artillery available to the Ming navy until the advent of Hong Yi Pao.
