It was a few days ago, at my school. I was explaining about baduk to my new Russian friend. One Chinese girl, who were sitting not far from us, by chance overheard us. She asked me, "Oh, you are a professional chess player?" So I said, "No. I play weiqi." "You play what?" "Whe-ii-chi--" "Ah, weiqi." 


I turned back to my Russian friend, and said, "You may haven't heard of it because it's mostly popular in China, Korea and Japan." Then suddenly the Chinese girl said, "It's not popular in China." Being embarrassed, I said "Yes, it is." But when she said "Come on, I am Chinese," I didn't know what to say. 


I am still thinking what I should say if similar situations happen again. What would you say if you were me?
