Wong was brought to the Ancient One when he was only 4 years old by his father, Hamir the Hermit. While there he became a martial arts master, but doesn't get a chance to practice much as a manservant. Upon reaching adulthood, Wong was sent to America to serve Dr. Strange. While there, Strange has become the new Sorcerer Supreme.
Wong was created by Stan Lee and Steve Ditko and first appeared in Strange Tales #110 (1963).

Later Wong was captured by an other-dimensional sorcerer called the Shadowqueen. Dr. Strange rescued Wong, who helped him defeat her.
Wong and Topaz were then captured by Urthona, in an effort to obtain certain mystic talismans and texts. While there Wong was tortured and disfigured by the fiend. To rescue them, Strange attempted to destroy the artifacts but instead sent the to Agamotto. With the artifacts no longer on Earth, an ancient spell was lifted that protected Earth from various, powerful entities.
Strange then cast a spell to make everyone think he was dead, leaving Wong in charge of his estate. During this period Strange defeated many of the creatures freed by the missing artifacts, like Shuma-Gorath. After Strange defeated Shuma-Gorath, he reversed the spell. Wong was overjoyed to see his master was still alive. Soon the rest of the world learned Strange was still alive.
Bride of Wong
When Imei Chang, Wong's intended bride, was turned into a horrible demonic creature, Wong asked Strange for help. Unfortunately Strange was tied up with other, more pressing matters. This resulted in a small falling out between Wong and Strange. When Strange eventually had the time to aid his long time ally, he found that Imei was dead and that this was just a creature imitating her.
Powers and Abilities
Wong has no superhuman powers, he has great knowledge about the magical and supernatural world. He is also very adept in martial arts having trained Dr. Strange in them. Even Strange himself said 'In some areas he's my servant, in others, my master'. Meaning that Wong trained him.
