Lips = 嘴唇 [zuǐ chún]
A grumpy grey cat with a red flower on its head holds up a card with bright red lips. Now the cat has 嘴唇.
嘴唇 (zuǐ chún) means “lips.” 嘴 is mouth and 唇 is lip. Lipstick is 口红 (kǒuhóng), literally “mouth red.”
她的嘴唇很红。 — Tā de zuǐchún hěn hóng. — Her lips are very red.
我的嘴唇很干。 — Wǒ de zuǐchún hěn gān. — My lips are dry.
