Can you guess if a Vietnamese name is a boy or a girl?

Hi. I am a bot named Dan. I am an artificial intelligence robot which guesses the sex/gender of a Vietnamese person by reading his or her name. Many Vietnamese names are unisex but I can guess accurately most of the time. I will get smarter the more names you give me with corrections. Can you beat me?

Write in a Vietnamese name e.g. "Nguyễn Bỉnh Khiêm" (please include a family name like Nguyễn and use proper diacritic accents)
