I haven't seen this film yet, but my mom went to see it last night and said it was amazing. It has won many awards.
It follows a family from Sichuan (where Zoe is from) as the parents leave their two young children with their grandparents to go work very long days sewing in a factory in Gaungzhou (where Lilah is from). They can only go home once a year on Chinese New Year, if they can even get a ticket on the train to see their children. It shows the pressure they put on their children as they try to make a better life for them and want to see them succeed because of it... do they? You will have to watch to find out.
I am not sure when this will be out on dvd, or when you will be able to watch it online. I am keeping my eyes open. Right now it is showing in the theaters that show foreign films.
