How to ask the gender of someone if you have to? [closed]

Solution 1:

I wouldn't beat around the bush. You can ask directly. Maybe a polite way to put the question: "I'm sorry, but I'm unfamiliar with the name Xiao Yi. Is it mister or miss?"

Solution 2:

The best way to be delicate in such a situation is to express your intention and admit ignorance. "I would like to use a proper form of address, but I don't know if your name indicates a male or female person."

Solution 3:

"Pardon my ignorance, but what form of address should I use with that name, Mr. of Ms.?"
