What is a good C-drama recommendation for an avid historical K-drama watcher ?

Hi !

I am an avid saeguk (historical) k-drama watcher, and I have struggled to find some worthy shows lately. I have never watched a c-drama and I feel like I have been missing out ! If possible, I would like you to make recommendations to help historical k-drama watchers like me dive into the world of c-dramas. Preferably an epic tear inducing tale, with good intrigue and adventure. Some of my favourite shows include My Dearest and The Red Sleeve.

Thank you so much for your recommendations !
