Bowie Cheung (張寶兒) recorded the show, Sidewalk Scientist (學是學非) at TV City on 11th May. When mentioned about buying luxurious mansion with her boyfriend, Benjamin Yuen (袁偉豪), she explained it was for an investment and did not specially buy it for him on his birthday. Bowie needed to discuss with Benjamin whether it was for staying or other purposes.

Reminding that Crystal Fung (馮盈盈) and her boyfriend parted their ways after buying a flat together, Bowie replied with confidence: “It is an example only. I am worried about the payment for the flat and it is a good idea to ask Crystal for her experiences.” She added Benjamin and she dated for 3 years but had no marriage plan and prepared a surprise for him on his birthday.
