老鼠 (lǎo shǔ): mouse

In the middle of the night, I heard rustling sounds from the kitchen. When I turned on the light, I saw a mouse crawling out of the trash can.

Grandma said that when she was little, her family was poor, and sometimes they had to catch mice to eat.

In laboratories, scientists often use mice in experiments to study the effectiveness of new drugs.

As soon as the cat saw the mouse, it pounced, but unfortunately the mouse ran too fast and slipped into a hole.

The hygiene at this restaurant is terrible; there are actually mice running around in the kitchen. I will never come back.
