dangerous = 危险 [wēi xiǎn]

A little fish swims inside a glowing light bulb, and its shadow becomes a giant toothy fish chasing the shadow of a woman on a treadmill. Very 危险.

危险 (wēixiǎn) means “dangerous,” and also “danger.” 危 means peril and 险 means risky.

On signs you will see 危险 or 小心 (xiǎoxīn), “be careful.” The opposite is 安全 (ānquán), safe.

一个人晚上出去太危险了。 — Yí ge rén wǎnshang chūqu tài wēixiǎn le. — It’s too dangerous to go out alone at night.
