Jia Hongshen dating history

I actually saw this movie a couple of years ago and didn`t really understood if the actors in the movie were in fact the real people and if this movie were actually based on facts. Over the years I still thought of this movie so i decided to look it up. I finally do get the movie and the actual storyline that he had to go through really impressed me. I would just like to say that I have never ever thought of the brilliant idea having the real people to play themselves for the film. It could have brought back some really bad times in their lives but because this movie was great in every way, poeple can really learn from this film. Thank you, Jia Hongsheng for sharing real fans of real movies and your family really reminded me of true Chinese parents that loves their families and children.
