In the latest episode of Hong Kong star Carina Lau's talkshow Jia Ren Zi You Yue, which aired yesterday (March 21), she was asked by her guest, actress Charlie Yeung, on the most romantic thing her actor husband Tony Leung has done for her.

Carina, 58, shared that the couple are used to not seeing each other for long periods of time because of their work.

"There was one year where I was quite touched. Tony was filming in Vietnam at the time… My doorbell rang and when I opened the door, he used a camera to snap shots of my expressions!" she laughed.

Carina added: "He knows how to make me happy. Sometimes, when he is out of town for filming, he would fly back home for a few hours just to spend my birthday with me. Things like these make me feel that he's very thoughtful."

Carina and Tony, 61, started dating in 1989 after having first met on set in Hong Kong drama The Clones (1984). They married in Bhutan in 2008 after 19 years together.

In the first episode of the talk show, Carina told her guest, actress Athena Chu, that Tony only took the initiative when he was courting her.

Charlie, 49, also shared that when she and Carina filmed the Hong Kong movie Intimates (1997), which was shot mainly in Hangzhou, Tony visited Carina on set.
