In Mandarin Chinese, 猪 (Pinyin: zhū 🔊) means “pig”, “hog” or “boar”. It is also used figuratively, that is, as an insult. The Pig is one of the twelve-year cycle of animals which appear in the Chinese zodiac and is associated with the earthly branch 亥.
猪 is a simplified form of the traditional character 豬 which is a phono-semantic compound of semantic 豕 (“pig”, “boar”) and phonetic 者 (zhě). By some reason, in the simplified form, the semantic component mutated from 豕 (“pig”) to 犭 (“dog”). 猪肉 / 豬肉 (zhūròu 🔊) means “pork”.
