14.141

膺平（憶凝反蒼頡篇云二乳上骨也漢書韋昭曰胷四面高中心下處曰膺說文膺胷也從肉雁聲或從骨作𩪠古字也）。

Even chest (膺平: [the character 膺 (chest)] is 憶 [yi] + 凝 [ning] [yīng]. The Cang Jie Pian says: 'The bone above the two breasts.' In the Hanshu, Wei Zhao says: 'Where the chest is elevated on all four sides and sunken in the center, it is called 膺.' The Shuowen jiezi says: '膺 means chest.' It is composed of the flesh radical (月/肉) with 雁 as phonetic; it is also written with the bone radical as 𩪠 in ancient script).
