Autumn Moon (1992)

Twentysomething Japanese tourist, Tokio, comes to Hong Kong looking for good cuisine. He does all that the tourist is expected to do, but is disappointed with the food so far. By chance, he meets 15-year-old Pui Wai. She's been left behind with her eighty-year-old Granny, her parents too busy with their immigration problems in Canada. Differences in culture, language and age serve as no barrier, as Tokio finds a soulmate in Granny, Hong Kong cook extraordinaire. He discovers the secret to Granny's cooking and learns that she's known all along that her family will not be taking her to Canada when they leave.
