No, I'm not Chinese, nor do I have any Asian ancestry that I know of. Uma is Japanese for horse, and 馬 is the Kanjii for the word horse. うま is horse (uma) in hiragana, and this ウマ is uma in Katakana. Kanjii in Japanese and Hanzi in Mandarin Chinese have similar or almost the same characters, but often have different pronunciations and meanings sometimes. Mǎ is the pronunciation for horse in Mandarin, and uses the same character, 馬. My current username on here means "puppy" in Mandarin Chinese, and the pronunciation is after the Hanzi characters.
