Our surnames are worth gold.
When kids disagree with each other, you might hear an exchange like this: “I swear if I lie to you, I’ll abandon my surname!” Or, “I swear, if I lose, I’ll no longer carry the surname my father has given me!” Or, “Promised? If you lose, you will drop your surname, and follow my surname?”
When a Chinese kid places his surname as a bet, you need to take him seriously.
Does it sound strange to you? As a child, when I argued or swore with the boy next door, we used the most valuable bid — our surnames. I’ve never heard an Englishman bet his surname: “OK, if you win, I’ll abandon my surname Smith and adopt your surname Barker.”
Surname is important. Sons are important because sons carry on the family surname and lineage. Sons carry incense sticks when worshipping the ancestors. They preside over ancestral rites, especially during the Tomb Sweeping Day.
