It is said the movie started to film five years ago and completed in 2015, but for some reasons not until recently did it have premiere in China's Mainland. It's a commercial film but seemingly a biopic in which the stories of four Tsinghua guys with characteristic Zeitgeist of Nationalist China are told. They are real figures or the prototypes to copy. Apparently, so far I haven't had the chance to watch the movie either in theater or online. It's ok; someday I will.
Attached below is a report about the movie written by some critic; it concerns not only the movie itself, but also other things that are worth your while to read it, as well as relative links, at:
