1. Kim: The Gold Surname

There is a Korean saying: "If you throw a stone from Namsan Mountain in Seoul, it will hit a Mr. Kim."

Kim is the most common surname, held by about 21.5% of the population.

The character for Kim (金) means "Gold". The two main clans are Gimhae Kim and Gyeongju Kim.

Historically, "Kim" and "Gold" share the same root meaning of brilliance and preciousness.

2. Gimhae Kim: The Golden Egg from Heaven

In 42 AD, a mysterious voice was heard at Gujibong Peak.

A golden box wrapped in red cloth descended from the sky, containing 6 golden eggs.

The first child to hatch was King Suro, who founded the Gaya Kingdom and became the ancestor of the Gimhae Kim clan.

3. Gyeongju Kim: The Golden Box in the Forest

In 65 AD, the King of Silla heard a rooster crowing in the forest (Gyerim).

He found a golden box hanging from a tree branch, with a white rooster crowing beneath it.

Inside was a baby boy named Alji. He became the ancestor of the Gyeongju Kim clan.

4. Kims in Modern Times

In the past, people with the same clan origin (Bon-gwan) could not marry each other.

Today, laws have changed, and marriage is allowed unless the couple is closely related (within 8 degrees).

From BTS members (V, Jin, RM) to Blackpink (Jennie, Jisoo), Kims are famous worldwide!
