烟花 (yān huā): fireworks; prostitute (esp. in Yuan theater)

On New Year's Eve, the children ran into the yard to watch the fireworks; the colorful lights lit up the entire night sky, and everyone jumped and shouted with excitement.

On National Day evening, my family and I stood by the river, enjoying the fireworks and taking photos as keepsakes; at that moment I felt especially happy.

To celebrate the company's tenth anniversary, the boss specially arranged for a large fireworks display in the square; the scene was spectacular.

Although fireworks are beautiful, they leave a lot of smoke in the air after being set off, so many cities now prohibit setting them off in urban areas.
