Wu Han's father

Wu Han's father was the husband of Wu Han's mother and the father of Wu Han and his sister. Prior or around 1933, this man and his family, sans his son, contracted an outbreak of influenza and died, leading Wu Han to study political science.

Behind the scenes
James Kahn's novelization of Indiana Jones and the Temple of Doom states that following Wu Han's death, Indy would send money to his family, but as Indiana Jones and the Dinosaur Eggs revealed, Wu Han's family, including his father, had all died by that point. Wheter Wu Han had more relatives or this has been retconned has yet to be established by Lucasfilm Ltd.

In addition Kahn's novel reveals that Wu Han is half-Chinese and half-Dutch, though it's not known wheter his father was Chinese and his mother was Dutch or vice versa.
