To add insult to injury, Fung, 46, tagged Shu in the post and wrote on Instagram: "Happy Birthday to my beautiful wife? Keep laughing together. Forever young!"
Shu, of course, did not share the photo on her social-media accounts, but she left three syringe emojis under Fung's post. Some netizens joked that she is waiting for an opportunity to strike back at the
Gen-X Cops (1999) actor.
Last year, Fung posted on social media a photo of himself and a sleeping Shu, but with her face covered by a cap, to mark her birthday.
The move came after Shu posted an unglamorous photo of Fung sleeping on a plane on the first day of Chinese New Year in January last year.
