2. Goodbye My Princess vs 东宫 (Eastern Palace)
I think the english title is too straightforward (straight to the ending), I prefer the Chinese title as most of the conflicts revolve around the crown prince and happen in Eastern Palace (crown prince's residence).
3. Best Choice Ever vs 承欢记 (Story of (Mai) Cheng Huan)
Maybe it's because there's so many drama with FL's name in the title so that they change this one. I think the english title is too vague. Which choice is better, the man (but they don't even think about being married), the job (which is actually being served to her in a plate), or the FL's way of living? Maybe the filial piety?
4. Love o2o vs 微微一笑很倾城 (Wei Wei's One Smile is Very Alluring)
I just know that Love o2o is Love offline to offline. Which is not exactly right for the drama as only a few early episodes they don't meet online.
