@ikeno_kaeru China and Taiwan also have this last name '河', they pronounce Wu or Ho. Only Korean or those who have Korean as their Origin pronounce this name 'Ha'.
@ikeno_kaeru Thanks for finding out this photo of Asian!
I could figured out that the man called Andy Ha is not the British man but Korean.
This last name 'Ha' (河) is a typical Korean name. In my old high school days in California, there was the Korea guy who had this last name.
