#namefacts In Chinese, many people have a two-character first name. Some Chinese families like to have all the children in the same generation use the same first character in their first name. So my name, my sister's name and all my cousins' names begin with "子."
My English name is Dominic because my Chinese names has a "duh" sound in it. My mother said I could be either "Dominic" or "Douglas." I didn't want to be called "Douglas" because it sounds like "dog."
That's why Dominic is here. #namefacts
