According to the Japanese spelling, Yang is pronounced [jɑːŋ], not [jæŋ] as is more common for the word yang as it is typically used in English. This is pronunciation is reconfirmed in the English localization of the DS version.
In all his appearances and artwork Yang sports a blond mustache and bald head with braided ponytail. In Final Fantasy IV and his Amano artwork he is shirtless, with red bands on his wrists; red pants tied at the ankle; a yellow sash around his waist, and flat brown shoes. He also wears red earrings, and has a red tattoo on his left shoulder. In The After Years he retains the red pants, but now wears a red and purple sash over his left shoulder, and another tied to his left thigh. He wears white boots, and his hair and mustache are substantially longer.
Taciturn, humble and polite, yet fiercely protective, Yang has no wish to hurt others or involve them in situations where they could be in danger, but is always grateful for assistance. His high standing in Fabul means that he has garnered much respect, and the only person he appears to quail before the might of is his own wife. In both Interlude and The After Years, it is demonstrated that Yang copes with stressful situations where he is of no use by training himself and the other monks, though in the former he is unable to stop himself from rushing to Sheila's side as she gives birth. During The After Years he initially refuses to train Ursula, believing she has no need to train for war, but after witnessing her selfless protection of the monks accompanying her, he takes her on as a disciple. However he warns that now she is just another student, not a daughter or a princess, and demonstrates this when training her in the game's ending. According to Sheila, Yang admitted to her privately "how can I believe in my people's future if I cannot even believe in my own daughter?"
