Is it true that two people with the same surname cannot get married in Korea?

1. Koreans' surnames are China surnames. Before the Japanese occupation, South Korea used Chinese without translation. Most Korean families are also descendants of immigrants from China.

2. It is a tradition in China not to get married with the same surname, which is stipulated by Zhou Li. Because in the past, the same surname was basically from the same family, and the blood relationship was very close, so it was stipulated that the same surname should not be married. Now people in China don't pay attention to this, because even if they share the same surname, their blood relationship is far away. Koreans just keep the tradition of China. Unmarried people with the same surname mean that people with the same surname can't get married. If your surname is Zhang, you can't marry anyone with the surname Zhang all over the world.
