The ancients often called themselves Yu. Does this modesty mean that they are the rest?

The rest of the words are hieroglyphics. In Oracle Bone Inscriptions, the shape of a house supported by trees is synonymous with the word "shed". Therefore, the word Yu originally meant housing, but this meaning has long since disappeared. Later generations often use borrowing as the first personal pronoun. Such as "Erya Shi Xia": "Yu, I am also." Use the house where I live (my home) as the pronoun of "I". As for surplus, we should do more "surplus" in ancient books. Of course, there are precedents for simplifying the remainder into the remainder.
