瓜子 (guā zǐ): melon seed; seeds of pumpkin, watermelon or sunflower etc, roasted and flavored, consumed as a snack

During the Spring Festival, every household sets out a plate of melon seeds on the table; when guests arrive, they chat and crack them open.

While watching a movie, she bought a bag of melon seeds, but before the movie was even half over, she had eaten them all.

Grandpa sat in the yard basking in the sun, holding a handful of melon seeds and cracking them slowly, looking very relaxed.

This kind of melon seed is salty, and it tastes so fragrant and crispy that I unknowingly ate a whole big bag.
