Big, green-striped melons with sweet, juicy red flesh, the fruit of summer, eaten in slices. The rind is sometimes peeled and stir-fried, stewed or pickled as a vegetable.
China produces and consumes more watermelon than any other country. Tapping a watermelon to check ripeness by sound (听声音) is a common skill - a hollow sound means it's ripe.
history
The name 西瓜 (western melon) reflects that watermelons were introduced to China from Central Asia. Similarly, 南瓜 (pumpkin) means 'southern melon.'
