Wong Fei-hung
Siu-kwan was the Western-educated aunt and love interest of the protagonist, Chinese folk hero Wong Fei-hung in the film "Once Upon a Time in China". Wong Fei-hung respectfully calls Siu-kwan "Thirteenth Aunt", in accordance with Chinese traditions emphasizing generations and family status. In imperial China it was considered disrespectful to refer to Thirteenth Aunt as "Siu-kwan", despite her later insistence that Wong Fei-hung do so. Their romance is forbidden since they are considered relatives due to Siu-kwan's father was a blood brother of Wong's grandfather.
