For a china movie, it's actually not bad. Not even going to care about how the script plays out because there are already hand full of film with exactly the same formula.
the female lead, happens to be a 10 yr old girl. She did an amazing job with tears and just being a daddy's girl.
Filming + directing was decent, just the boxing formulas has bee done to death. People praised it for epic crying + tear jerking + sad movie, but all in all... meh
7/10 for chinese movie to say the lesat.
