Among chinese dramas, Hong Kong produce the best quality. The worst are dramas from China (Mainland) and Singapore. Acting skills from these two countries are horrible and should avoid at all times. Taiwan ones are so so and I dont really watch them.
There are actually some good recent dramas ongoing and you could check out at TVB official website for more information.
I'm currently watching "A Journey Called Life", a modern drama about the ups and downs on family ties, love relationship and work politics. Some noticable actor/actress like Steven Ma, Linda Chung, Fala Chen and old timer fatty Kent Cheng in this series.
