Brilliant performance from the casts especially Zhang Zi yi , her performance was very natural and yet exciting. All the emotions on the different scenes be it happy , strong and innocent are portrayed nicely. Yes, that 30 and 15 year old question again.... no matter how it's just a movie/drqama so what do you expect ? her acting skill has greatly overcome the downfall of age difference . It didnt affect me as much , i still enjoyed the movie and the casts really well. Enjoyed every bits of it . Its one of the big production drama, not much dramas you'll find as detailed as this. Good scenery , clothes, colours.
