三缸盆瓶 Vat, Basin, and Vase
虎力大仙愛強,就擡一口大缸,放在殿上;鹿力大仙端一砂盆,安在供桌之上;羊力大仙把花瓶摘了花,移在中間。行者道:「你們都出殿前,掩上格子,不可洩了天機,好留與你些聖水。」眾道一齊跪伏丹墀之下,掩了殿門。虎力大仙爱强,就抬一口大缸,放在殿上;鹿力大仙端一砂盆,安在供桌之上;羊力大仙把花瓶摘了花,移在中间。行者道:「你们都出殿前,掩上格子,不可泄了天机,好留与你些圣水。」众道一齐跪伏丹墀之下,掩了殿门。

Wukong caps the staging with the line every confidence trick needs -- everybody out, shut the door, this must not be seen. Dressed as reverence for a heavenly secret, it is simply a request for privacy, and they grant it gladly. With 掩了殿門 the doors close on the three of them.
