橘柚（上居聿反說文云果名也周禮云踰江淮北化為枳地氣然也下余救反字書云似橘而大皮厚廣志云成都柚大如斗郭注爾雅云柚似橙而酢生江南也二字並從木矞由皆聲也）。

橘柚 (The first character has the fanqie 居聿 [jū + yù]. The Shuowen jiezi states: 'The name of a fruit.' The Zhouli states: 'Crossing the Huai River to the north, they turn into trifoliate oranges; it is due to the climate of the earth.' The second character has the fanqie 余救 [yú + jiù]. The Zishu states: 'Resembling an orange but larger, with a thick peel.' The Guangzhi states: 'The pomelos of Chengdu are as large as peck measures.' Guo [Pu's] commentary on the Erya states: 'The pomelo resembles a bitter orange and is sour; it grows south of the Yangtze.' Both characters are derived from 木 [tree] with 矞 and 由 respectively as phonetics).
