New Style in Cantonese Opera?

Recently saw 2 different Mun Moh Sang in Singapore. Overall the show is OK except one common thing - both of these artist do not 'hold' the last beat of the percussion with 'strength'. Is in a new trend from Hong Kong (both artist are from Hong Kong). It looks abit 'soft' for a 'mun moh sang' to act this way.

Prank calls again

Yes, today there is another call. Another girl in my office receive this type of call again. Most fortunate for her, she dont understand the language the girl is speaking and only understands the word 'mama mama' Unable to get any response, the girl/caller put down the phone. Still wondering should we report this again? What can the police do? I believe nothing since we cannot trace the call.
