culture
肠粉 (rice noodle rolls) is a beloved Cantonese dim sum dish. 灌肠 (guànchang) is a famous Beijing street snack made from starch stuffed in sausage casing.
Left radical ⺼ is the flesh/meat side-form (visually identical to 月 'moon' but historically distinct — derived from 肉). It marks 肠 as a body-organ word: the intestines. Same ⺼ radical groups 肠 with the body-part family — 肝 (liver), 肺 (lungs), 胃 (stomach), 脏 (organ) — all interior anatomy.
Right phonetic is the simplified contraction of 昜 (yáng, rising sun) — standalone 昜 has nine strokes but here only three remain after the 1956 simplification reform. Sound shifted yáng → cháng through onset palatalization. The same simplified 3-stroke right-side appears identically in 扬 (yáng, raise), 汤 (tāng, soup), 场 (chǎng, field), 伤 (shāng, injure) — all share this contracted phonetic.
