  • What is a surname and what do you think is the most common one in the world? 
“A surname is a name added to a given name and is part of a personal name. In many cases, a surname is a family name. Some surnames are rare, and the others are so common that their population can be measured by millions. This is the most common surname in the world:
  •  Li or Lee – More Than 100 Million People
    It is a widespread surname in China, with about 7.9 percent of the Chinese population possessing this family name. Li is the most common surname for the Hakka Chinese. A Korean surname that uses the same Chinese character, which is often romanized as Lee, is the second most common Korean surname, after Kim. Both the Korean family name Lee and the Vietnamese family name Lý was derived from the same Chinese character as the Chinese surname. Taken collectively, these surnames make Li the most common surname in the world.”
