南 - Nan2 - South

南瓜 - Nan2 Gua1 - South Melon — Pumpkin

西瓜 - Xi1 Gua1 - West Melon — Watermelon

Maybe this is why in Monkey Kung Fu the teacher refers to the things he makes the guy shave as part of his training as “pumpkins” even though they are CLEARLY watermelons.

And strangely 黃瓜 - Huang2 Gua1 - Yellow Melon — Cucumber. But… they aren’t yellow?!
