This gold bowl (more precisely, a Yu (盂)) was produced by repoussé and formed into a shape similar to the traditional earthen begging bowl of Buddhists. However, though a Buddhist, Prince Zhuang was not a monk. In addition, in form and size, the bowl is almost identical to the gold rinsing bowl found in Emperor Wanli's tomb in the Dingling Mausoleum. Therefore, archeologists believe it was used for rinsing the mouth.
