This drama is well written and well executed. The pacing is just right. Clues are revealed logically and in a way that is sophisticated, yet easy to follow.

I'm not a big fan of overly romantic drama. I like it when something else is the main point. There was just enough romance and it wasn't overly done.

The secondary characters are fun to watch as well. They're quite funny.

It was interesting to watch a somewhat medical drama from the Tang and Song Dynasty. I don't know how accurate it is to the times, but they seemed to have a good grasp of human physiology and disease processes.

A delight to watch. I want to go back now and see if there were any clues missed!
