弱齔（禮記云二十曰弱冠下初謹反鄭注周禮男子八歲毀齒曰齓說文從齒七聲集文作齓非也）。

弱齔 [ruòchèn] (The Liji says: 'At twenty, one is called "weak" [ruò] and takes the cap.' The second character has the fanqie chu + jin. Zheng's commentary on the Zhouli states: 'When a boy loses his baby teeth at eight years old, it is called chèn.' The Shuowen says: 'It has the radical 齒 (teeth) and qi as phonetic.' The Jiwen written as 齓 is incorrect).
