Clock = 钟 [zhōng]

A sketch of a Las Vegas casino comes with a speech bubble claiming you won’t find a single 钟 inside.

钟 (zhōng) means “clock,” the kind on a wall or a tower, and also “bell.” A wristwatch is 手表 (shǒubiǎo).

钟 also shows up in time words: 三点钟 (sān diǎnzhōng), three o’clock; 十分钟 (shí fēnzhōng), ten minutes.

墙上有一个钟。 — Qiáng shang yǒu yí ge zhōng. — There is a clock on the wall.

我等了十分钟。 — Wǒ děng le shí fēnzhōng. — I waited ten minutes.
