Dìdi (弟弟)

For most of the movie, the son, Didi, only spoke in English, while the mother in Mandarin. Only at the very end, the mother bridged that gap by speaking the language her son has embraced, to which Didi followed by greeting her in Mandarin. That shit made me cry!!! After a very uncomfortable hour and a half, they wrapped it up quite nicely and it got me sobbing. Love this movie.
