喂，您找哪位? Hello, who are you looking for?
我找王老五。I want to talk to Wang Lao Wu.
Notes: In China, if there are five kids in the family, we call the oldest one 老大, literally “old big one”; the second one we called 老二, literally “old number two”…老五 “old number five”. 王老五means, his family name is Wang, and he is the fifth son in Wang’s family.
