<b>My father's lineage is Chinese, but my mother's is Vietnamese, then I have relation between the two ethnicities.</b><br/><br/>How can you talk about ancestor's relation in more natural way. <br/><br/>The sentence above is my own word if I have to talk about it.<br/><br/>However, in a very natural English, I have no clue.<br/><br/>Can you give me some example of how to talk about this kind of topic naturally.<br/><br/>I'm afraid some of my word choices are ridiculous or awkward.<br/><br/>Thank you.
