Hong Kong's first daughter Leung Chai-yan, the offspring of the island's Chief Executive CY Leung, has been brought under the spotlight for slapping her mother in public after a Halloween party on Sunday.

Leung celebrated Halloween with two of her female friends at Lan Kwai Fong. They walked out of a bar at 3 a.m. and were going to leave with a Taxi. But Leung reportedly had a quarrel with the driver of the taxi and he refused to take them. The group then waited for Leung's mother Regina Tong to come and pick them up.

When Regina arrived with many reporters, her 24-year-old daughter got angry.

 "What the f*** wrong with you? Stop taking photos of my friends!" Leung shouted to the press in Cantonese.

Dressed in a Halloween costume and ghost make-up, Leung suddenly slapped her mother twice as Regina was trying to help her get into the vehicle.

Leung then refused to let her mother guide her into the car. "You know this mom is not my actual biological mother," she told the press before leaving with a male friend identified as Arthur. Her mother quickly left on her own.
