壑空（上訶各反顧野王云壑谿谷也郭注爾雅云壑坑塹丘墟耳說文壑溝也或作叡從土叡叡亦聲經作𭐋俗字也）。

Hekong 壑空 (the first syllable is read with the fanqie 訶各. Gu Yewang says: "A 壑 is a mountain ravine or valley." Guo's commentary to the Erya says: "A 壑 is simply a pit, trench, mound, or ruins." The Shuowen says: "A 壑 is a ditch; it is also written 叡, formed from 土 [earth] with 叡; 叡 is also phonetic." The scripture writing it as 𭐋 is a vulgar form).
