27.379

於某（莫補反又莫厚反尚書尒元孫某孔安國某名也臣諱君故曰某名凡不知名皆云某）。

For so-and-so (於某: [某 is pronounced with the fanqie] 莫補 [mǔ], and also 莫厚 [mǒu]. The Shangshu says: 'Your great-great-grandson, so-and-so.' Kong Anguo says: *mou* stands for the name; because a minister avoids uttering the lord's name, he says 'so-and-so's name.' Whenever a name is unknown, it is always called *mou*).
