A young Taiwanese civil servant is supposed to write a manual about mainland customs. After ten revisions, his boss gives him an ultimatum, get it right or get a new job. That not he runs into a young mainland woman at the dumpling shop and makes a deal. He will help her find her grandmother's first love and she will help him finish the manual. Their search probes the meaning of love, growing old and the cultural differences between Taiwanese and mainlanders.—Mike Wexler
