TVB actor Benjamin Yuen’s younger son is found with dark bruiselike marks all over his body, sparking shock and concern among netizens.

TVB actor Benjamin Yuen Wai-ho, 44, has been married to Bowie Cheung for five years. The couple have two sons—Hayven (nicknamed “Yuen Gu Luk”), who is two years old, and their younger son “Yuen Dam Dam,” who is just two months old. They frequently share family moments on social media.

Recently, Cheung posted a short video via their child’s social account. The baby appeared chubby and adorable, with impressive upper-body strength, but viewers also noticed several bluish-dark patches on his skin, which quickly sparked discussion online. In her caption, Cheung joked that despite being so small, the baby held a “half plank” position for nearly ten minutes—so long that even she felt tired.

In the clip, the baby is seen lying on his stomach in a crib, looking around alertly and making sounds while focusing on colorful cards. However, some commenters expressed surprise at the bluish patches visible on areas such as the shoulders, underarms, waist, ankles, and even across the buttocks.

Others responded that the marks may be a common type of birthmark in newborns, often known as “Mongolian spots” (dermal melanocytosis). These typically fade gradually as a child grows and often become much lighter or disappear naturally by around ages three to four.
