十誦律云。鉢半鉢大鍵𨩲（鍵音處。𨩲音咨。經音疏云。鉢中之小鉢。助鉢用故）小鍵𨩲（僧祇同）○四分律云。鍵𨩲入小鉢。小鉢入次鉢。次鉢入大鉢（此律言。小鉢即十誦大鍵𨩲也。次鉢即半鉢也。淮諸律四事可見也。今呼為𮣊子。𮣊音訓切。𭨂云鐵類也。非器故）。

The Ten-Recitation Vinaya says: Bowl, half-bowl, large kuànduō (kuàn is pronounced chu, duō is pronounced zi; the Commentary on the Sounds and Meanings of the Scriptures says: a small bowl within the bowl, used to assist the bowl), and small kuànduō (the Mahāsāṃghika is the same). The Four-Part Vinaya says: The kuànduō goes into the small bowl, the small bowl into the middle bowl, and the middle bowl into the large bowl. (What this Vinaya calls the small bowl is the large kuànduō of the Ten-Recitation Vinaya; the middle bowl is the half-bowl. Comparing the various vinayas, the four items can be seen. Today they are called xiàzi; xià has the fanqie xun-jie. Kuàn says it is a kind of iron, not a vessel).
