English: Bitto Singh Hartihan was born and raised in Hong Kong. He enrolled in local schools, ever working at an air cargo company owned by an Indian. Although he mastered the workflow as he has moved from entry-level to high-end positions, he left due to differences of opinion on some issues with other colleagues when his boss handed over the company to the Hong Kong management team.
And then, Bitto entered the film industry by chance. He was just helping an assistant director of "Tactical Unit: Partners", Keith Chan Cheuk-kei for researching at first. During the audition, the director couldn't pick up one suitable South Asian for a role, so he was given a shot instead. As a keen basketball coach, he established B2 basketball academy for training kids and teenagers.
