|It's a straightforward assignment, 47.|
Tzun, also known as Zun, is Lee Hong's personal bodyguard and his right-hand man, thus he will escorts him everywhere to guard him from any possible danger, including tasting Lee Hong's food for poison.
He is Chinese, bald, overweight and clothed in a red dressing gown. Despite his weight, he is as fast and agile as any other person.
- He has the ability to look through guard disguises that 47 uses, one of the only characters in Codename 47 with this ability (another is the Hong Kong Chief of Police).
- Although he is Lee Hong's bodyguard, he will not go into his room.
- Likely a result of being so overweight, he can withstand more the average amount of gunshots needed to kill a man. Furthermore, it is not possible to kill him with Lee Hong's poisoned sword in combat (but a strike from behind will still kill Tzun in one blow).
- In Hitman Contracts, Zun's random room checks can be used against him. At some point he does go down into the basement where the speed boat is; this provides a perfect opportunity to quietly take him down using the fiberwire and leave no risk of someone discovering the body.
