Short answers, pulled from the story.
Chun-Li was created by Akira Nishitani and Akira Yasuda and first released in 1991 in Street Fighter II: The World Warrior. The development team had only five weeks to finalize her design before the game's release.
Chun-Li's father was a police inspector murdered by M. Bison, the leader of the criminal organization Shadaloo. She is an Interpol officer seeking revenge for his death and pursuing justice across national borders.
Chun-Li originally wore pants until the final sprite creation phase when Akira Yasuda changed them to tights. The final design features a blue qipao modified for movement, ox horn hairstyle, and spiked bracelets.
Chun-Li appeared in the 1994 Street Fighter film played by Ming-Na Wen and the 2009 Street Fighter: The Legend of Chun-Li played by Kristin Kreuk. The 1994 film gave her the surname Zang Chun-Li while the 2009 film changed her last name to Xiang.
The Spinning Bird Kick was initially too powerful and cut from the original game after the team ran out of time. It was restored in later versions such as Champion Edition and became one of her most recognizable moves.
In Street Fighter 6, Chun-Li continues to raise Li-Fen and train students in Metro City's Chinatown district. She is also promoted to become a director of Interpol while maintaining her status as one of the most powerful characters in the game.
