Háokēng (moat and trench) (the first character has the fanqie hú + dāo; also written as 濠. The Shuowen jiezi says: "A city moat." Dictionaries say: "A moat without water is huáng, with water is háo." The Vinaya text writes it with the "earth" radical as 壕, which is a popular character. Without water it is a huáng, with water it is a háo. The second character has the fanqie kè + gēng. The Qieyun says: "A steep trench." The Erya says: "Kēng means void." Guo's commentary says: "Kēng means trench." The Vinaya text writes it as 坭坑, both of which are popular scribal errors).
