I have been trying to remember this movie for years. It’s likely from the 90’s as that was when I remember watching it, and all I can remember is that is was set in Asia(likely to be china) where many of the characters wore those stereotypical straw triangle hat things and works on fields. The plot line focused on a massive drought in their community and the ending had an eastern style dragon (blue coloured I think – like the one from Spirited Away) who made it rain, at last for these people. I think one kid went on a journey to find the dragon? And the dragon flew over the land and made it rain. I’m seriously racking my brain about this!!!!! 🙁
More details: It WAS in English, though set in Asia and it was in colour not black and white. It was a cartoon as well.
