Min Sun is a native of Shou Lung. She was raised by her father, Gi Sun. Her mother, Jin Sun, died of complications during childbirth. She was an only child, who learned to fight using farming weapons. She watched her father teach his techniques to other folks as a young child. When she got older, her father taught and practiced with her. Once the folks mastered their technique, they went off to defend Shou Lung. Some sought more adventure and set out for lands unknown to them.
Once Min mastered her training, she had skillfully deceived many others as well. She had dressed and appeared as a man. She told others that her name was Kwan Sun. They had believed it. They had battled with her as though she were a man. She couldn't let them know that she wasn't a man.
