I am currently watching Ode to Joy. I don't know why no one has mentioned it yet, because it is such a nice, warm feelgood drama with interesting and likeable characters. There's a bit of romance, and a little bit of business, and work problems, and it looks like someone is hiding something big from the main character... and mostly it's about friendship and, well, life. I'm almost halfway through and I've enjoyed it so much from the start.
My favourite (Chinese) drama so far is definitely Nirvana in Fire. It's a masterpiece.
The first Chinese drama I watched was Sound of the Desert and I loved it sooo much.I might be biased now but I think it's a great first Chinese drama! ;) It has a little bit of everything, I think. I also enjoyed The Disguiser.
One Chinese drama that I dropped was Boss & Me, but that just goes to show that we all have our own taste, I guess. I just didn't find it as "cute and fluffy" as it had been described to me.
