If you watch only one #cdrama please make it Winter Begonia (2020) with the brilliant Yin Sheng in the role of a famous Peking Opera star during the Republican era as Japan invades. 

It is now on Viki. 

You learn so much about Opera and the competing music troops. It is roughly based on actual historical opera stars. With musical scores from the era. 

But you also get to watch a truly gifted actor given room to just fill the screen with his power. A great great role.
