The eight-minute film is set in Toronto and features many of the city’s landmarks.
“Bao” tells the story of an aging Chinese mom suffering from empty-nest syndrome who gets another chance at motherhood when one of her dumplings springs to life.
Shi beat out two other animated films by Canadians for the Oscar — “Weekends” by Hamilton-born Trevor Jimenez and “Animal Behaviour” by Vancouver-based couple David Fine and Alison Snowden.

“To all of the nerdy girls out there who hide behind their sketchbooks — don’t be afraid to tell your stories to the world,” Shi said onstage in her acceptance speech.
“You’re going to freak people out but you’ll probably connect with them, too, and that’s an amazing feeling to have. Thank you to (executive producer) Pete Docter for believing in my weirdness and for giving me a voice at the studio.”
Many people took to Twitter to celebrate “Bao’s” win.
Shi was born in China and moved to Toronto with her family at age two. She used her upbringing and love of food as inspiration for “Bao”, which played in theatres with “Incredibles 2.”
Shi shares the Oscar with producer Becky Neiman-Cobb.
