This is my list of Chinese historical/period/costume dramas so far.
10 Miles is really awesome if you can stick with it through your slump. If not, I suggest picking up any of the following:
The King's Woman. It's based on the first Chinese Emperor and his rumored relationship with a concubine. In real life, that relationship ended up being the basis for questioning the parentage of the third Emperor of China.
The Princess Wei Young is a similar to General & I in that Li Wei Young is an excellent strategist like Bai Ping Ting.
I'm currently watching Nirvana in Fire and really enjoying it. The main character is a male strategist. The cool thing is it has a currently airing sequel, Nirvana in Fire 2.
Happy watching with whatever you end up going with!
