In that movie, a kid is traveling alone with his panda, trying to find the valley of the panda, where it will be happy and free… Probably a foreing movie (Asian) from 1975-1984 I would say. At some point, they get attacked by a huge carnivorous plant. At the end, they find the valley and they run down a hill, running happily. I can’t find the title… Help!

Edited comment

The year does not match, but any chance it is “The Amazing Panda Adventure” (1995)? The scenario is somewhat similar to what you described.
