Factual errors: In the first scene where young Ying Ying met her future husband, the guy opened a watermelon which was totally seedless. The scene should be in later 1930s or early 1940s, based on the context. Very unlikely there was any seedless watermelons available in China at the time. Japanese scientists started seedless research in lab in 1938. It won't be widely available even in Japan market till after WWII.
