I guess this drama doesn't fulfill our expectation, that's why the rating is a bit low. But still its a good watching, especially wu jin yan. I think she is born for historical dramas.
At first, honestly i have low expectation for this series, even the rating is above 8.0 and i always don't trust it if its for cdrama. But after finished this, i can say this is masterpiece. Even it ends sadly which i don't like it, but still there is a lot of scenes that can be cherished along the story.
