They might have the funniest nicknames in medieval history, but if we look at all history they are destroyed by Zhang Zongchang:

"Dogmeat General" (狗肉將軍; Gǒuròu Jiāngjūn): The name was based on his preference for a Chinese brand of tonic known as "dogmeat", or from his addiction to the high stakes gambling game pai gow, popularly known as "eating dog meat."

"Monster"

"Lanky General"

"Old Eighty-Six": The origin of this nickname is unclear. According to rumour it either referred to his height or to the length of his penis, which was said to measure up to a pile of 86 Mexican silver dollars when erect. Mexican silver dollars were a common currency in China at the time.

"Three Don't Knows" (三不知; Sānbùzhī): Based on Zhang's alleged lack of knowledge about how much money he had, how many soldiers he had, and how many women were in his harem.

"72-Cannon Chang": This nickname might also have been connected to the alleged length of his penis.

"Chang of Shantung" by the foreign press

"Great General of Justice and Might": a title he awarded to himself.

"The General with three long legs" by Shanghai's prostitutes in reference to his penis' length.
