Never mind my list nor my favorites. It's probably updated last year

I do want to hear thai/chinese/taiwanese recommendation too^^

I hope the show is enjoyable to watch & worth the time :)

I'm looking for the same kind of drama x) but are you looking more for actions, thriller, romance...? 
Otherwise I really liked Evil Mind, and Decoded  (Chinese) but it's still men who are the lead ^^ 
- 如果蜗牛有爱情 When A Snail Falls in Love
- 班淑传奇 Ban Shu Legend (I doubt there are subs for this yet :(( that's why it's so underrated)

Not sure if you would mind jdramas but there will be way more examples for that~ ((sorry for the not-so helpful list))
Would highly highly recommend A Touch of Green. It's a Taiwanese period drama filled with strong female characters, some romance and lots of emotional pain, but extremely well-written. It's not been subbed in English though :( but if you can understand Chinese please do give it a try!! http://mydramalist.com/15192-a-touch-of-green

Also Legend of Lu Zhen, a historical Chinese drama with a strong feminist plot and a good dose of romance. Also not sure if this has been subbed into English though there is a higher probability it has than with A Touch of Green. http://mydramalist.com/4269-legend-of-lu-zhen

Prince of Lan Ling, also a Chinese historical drama, carries a similar feminist vibe in my opinion, though it may get a bit draggier halfway through. http://mydramalist.com/4033-prince-of-lan-ling

If you are considering some kdramas, I Hear Your Voice has a really strong plot and uniquely flawed female lead too. :) http://mydramalist.com/6993-i-hear-your-voice

An older kdrama suggestion would be Shining Inheritance. It may be a bit cliche in its premise, but I found the female lead to be refreshingly not weak at all.http://mydramalist.com/70-shining-inheritance

Hope this helps! >.

The Priness' Man --- great plot ...  smart, strong and very brave female! ... most perfect female lead!
Scarlet Heart --- great writing ... excellent!
Sound of the Desert --- good story ... she's tough and smart
Empress Ki --- excellent .... perfect first half, w/ minor plot holes in the second half
Queen Seon Dook  --- strong female lead and an Amazing female Villain!
East of Eden  --- melodrama, so maybe not what u want ... But Great revenge plot and all the women were strong and smart! .... especially Guk-Ja, brave, smart and clever ... she pursued him all the way!

Carnation biography of a really amazing woman from her early years until her death. Could easily be described as positive and feminist. https://vid.me/LbSu
Seirei no Moribito serious fantasy adventure action drama, sexism basically non-existent. Unusual, strong heroine as a bodyguard. http://imgur.com/a/0cI8F

Both the leads are women: they are strong and smart and calm. There's no screaming and yelling, there's almost no romance. It's about business and the plot is filled with intrigue like a sageuk set in modern times.  It's slow, so take your time with it, but the pace is necessary for the story.
WOW!! So much reply!^^ The descriptions sounds really great too! Thank you SO MUCH!! :-D
