Personally read the book, and have to say they did a great job in adapting the book, with the parts changed (knowing Chinese censorship). The acting was phenomenal. I have always loved Ding Yuxi but I think Musheng is a truly breakout and memorable role for him. He has the ability to portray the most complex of emotions, and what's most amazing is that you will be able to see all these myriad of emotions clearly as an audience. Esther Yu was also the perfect cast for the role, she was able to portray the cuteness naturally. Last thing, great kudos to the director and the team, many scenes were a cinematic masterpiece.
