Mother testifies in court: Kwong Kau once said if she dared sell the flat he would "kill the whole family"; mainland property and Rolls-Royce registered under Kwong Kau's name

In the case of the killing of Abby Choi, daughter-in-law of the founder of Tam's Yunnan Noodles, Cheung Yen-fa testified in the High Court that the mainland property and Rolls-Royce car registered in the name of defendant Kwong Kau. The two sides had disputes over selling the flat since June 2022, and Cheung once rebuked the other party as "thief old man". When footage of the day of Choi's killing was played in court, Cheung cried. The defence said the Kwong family had contributed to buying the flat, which she denied, saying "evidence must be presented".
