How did this drama get a 8.5 rating?

it is very disappointing. I really like historical costumed dramas and I also like Timmy Xu. The way this story was written and presented was very poor. The actresses chosen to play the parts are also bad. It is hard to believe that a seamstress can be important enough to cause the extend of jealousies like the drama wants you to believe.

I realize that it is a fictional story. But, his drama screen writing really needed improving. It's just a lot of yelling, cunning and snappy dialogues, it is not convincing. After a few episodes, I totally lost interest.
