吁嗟 (The first character has the fanqie 況于 [xū]. The Kaosheng states: '吁 is an exclamation of doubt or surprise; derived from 口 with 于 as phonetic.' In the Vinaya text it is written as 噓 with the sound 朽居 [xū], meaning to blow or exhale, which is not the character for 吁嗟. The second character has the fanqie 子邪 [jiē]. The Qieyun states: 'An exclamation of sighing or lamentation.').
