Second, Tony Leung Chiu Wai didn't show up because Tony Leung Chiu Wai was busy at work. At Carina Lau's sister-in-law's birthday party, we saw that Tony Leung Chiu Wai didn't show up, probably because Tony Leung Chiu Wai wasn't around Carina Lau at all. Because Tony Leung Chiu Wai, as an actor in the entertainment circle, wants to make movies for the life of the whole family, and at the same time, he also hopes to make more movies to realize his dream. So this time Tony Leung Chiu Wai didn't show up at her sister-in-law's birthday party, largely because Tony Leung Chiu Wai went to film. After all, this is not Carina Lau's birthday party, but his sister-in-law's birthday party. Tony Leung Chiu Wai's absence doesn't seem very important, but Carina Lau, as her sister, should attend, otherwise it will attract a lot of criticism.
Third, this is Carina Lau's parents' party. Of course, this time Tony Leung Chiu Wai didn't attend Carina Lau's sister-in-law's birthday party. Another possibility is that Tony Leung Chiu Wai thinks this is Carina Lau's parents' party, so he can't show up because he wants Carina Lau to spend his birthday with his family. After all, for so many years, every time Carina Lau holds a party, Tony Leung Chiu Wai basically goes to the scene to congratulate, which makes Carina Lau and her biological parents' relatives seem to have no independent space.
Generally speaking, Tony Leung Chiu Wai didn't attend Carina Lau's sister-in-law's birthday party this time, on the one hand, because Tony Leung Chiu Wai was too busy to attend, and on the other hand, because Tony Leung Chiu Wai wanted to give Carina Lau and her family some unique space.
