How do foreigners get their names? Are they randomly arranged?

Foreigners' names originated from nicknames based on human characteristics in ancient times, such as horse face, curly hair, squinting, forehead, reticence, kindness, intelligence, unsmiling and so on. Others come from the position of one person in the family, such as the boss and the old six.

Later, occupations also entered the ranks of nicknames, such as bookmakers, soldiers and blacksmiths. ...

Later, animals and plants also entered the ranks of people taking nicknames, such as wolf, grass, cat, cabbage and so on.
