Who's Shirley Chan? Sounds like a Hongkonger - she writes in Canto Chinese. And looks like she's a really good friend of Charlie Yeung, one of my favourite HK actresses in the mid-1990s. Well, this gives me hope that Charlie Yeung will appear in a Tangren production one day.
I'm quite surprise because I don't think LSS was in the Bu Bu cast line-up at all.

Zhang Ji Zhong, Yu Zheng etc publicize their cast list at least 2 months before filming.
