Loved the unique plot! All actors and actresses did a terrific job, especially the young kids - I cannot even count the number of times my eyes brimmed with tears at the emotional experience, and the number of times I burst out laughing at the funny scenes. The script was written very well. All four stories are masterpieces - the visual colour grading and shooting was also top quality. Would definitely recommend - this movie contains wonderful Chinese history and has an inspirational moral, about people sacrificing their personal gain for a better world. Much respect to all the unknown heroes who have toiled to make our world a better place!
