It is said that Gu Ailing's father belongs to RaySidney, Google's "No.5 employee", and it is also said that it belongs to David, the managing director of the $100 billion fund, but it is all speculation.

In an interview, Gu Ailing mentioned her family, basically talking about her mother and grandparents, and rarely mentioning her father. On February 5th, RaySidney, the fifth employee of Google, changed his Facebook profile to a photo taken with Gu Ailing as a child and commented: "Who can recognize this future superstar?" . But later I clarified that it was after Gu Ailing was born that he met Gu Yan (Gu Ailing's mother). Some netizens also speculated that Gu Ailing is the daughter of David, managing director of the $100 billion fund. Some netizens even speculated that Gu Ailing was a test-tube baby.
