How many children should Guan Wen have?

Rosamund Kwan's father has two children, one is his daughter Rosamund Kwan, and the other is Rosamund Kwan's younger brother.

Rosamund Kwan, formerly known as Guan Jiahui, changed his name to Rosamund Kwan after he entered the entertainment circle, and so did his younger brother Guan Shihua, formerly known as Guan Jiabo. He settled in the United States in his early years and worked in the insurance industry after returning to China. Unfortunately, his career changed, which caused him to owe huge debts and eventually declared bankruptcy. In order to transfer ownership, he chose to change his name to Guan Shihua, gave up his previous job and became a Feng Shui master. In recent years, he has established a personal website and started a new turning point.
