Story was based on the Chinese and Japanese conflicts which happened in the 20th centuries. So it may be a true story so if I see it as a true then I can't say much about the which I don't like because director also becomes helpless at this situation . He has to show the way story was .
Bit if it is not a true story and director pick the concept of Chinese and Japanese conflicts and how much Chinese people suffer because of this so he could give some more romantic scenes among the couple and her brother's story also . Except last two -three episodes ,it was not clear that who got female lead though by poster of the drama we can guess but still this had create confusion.
My favourite chay of the drama is Qu Man Ting . She was just Fabulous in the drama.
