Philip Ng (伍允龍) and Aka Chio (趙慧珊) promoted their new film, Undercover Punch and Gun (潛行者) at the radio station on 23rd August 2019. She praised he was very professional as an actor, action choreographer and film producer. Suggesting him to increase the fees, Philip said: “I am paid very little and it is to grant the wish of Andy On (安志杰) and Vanness Wu (吳建豪), because we become good friends after shooting Star Runner (少年阿虎) movie 16 years ago. Andy won best newcomer award while Vanness played the male lead for the first time, and I was assisting Chin Ka Lok (錢嘉樂) as vice-action choreographer. We really want to work together again.”

Aka expressed she specially learned martial arts from Philip and drew a design on her arm for a tattoo artist role during the audition. Philip confessed the role was given to Aka because of the preparation and outstanding performance.
