You have a gold coin, facing two countries, one is an honest country, and the other is a lying country. The honest country all tells the truth, and the lying country all lies. A gold coin can only ask one question. How would you ask?
Question supplement: You want to go to the honest country, how should you ask? Reason?

Q: Buddy, does your dad have a penis? Answer and I'll give you a gold coin.
Baidu it!
Simply ask someone coming from the opposite side, give him a gold coin: 'Excuse me, which road should I take to go to the country you live in?' If he is from the truth-telling country, he will tell you the road to the truth-telling country. If he is from the lying country, because he has to lie, he will also tell you the road to the truth-telling country. Therefore, if you go in the direction he says, you can't go wrong.
Can you stop Baidu-ing it and just think for yourself?
I answered twice... once telling that person to 'Baidu it' T_T, and once I actually Baidu'd it.
Insightful!
If you were from another country, where would you think the Honest Country is?
May I ask: If I give you a gold coin, will you tell the truth?
Ask one of the people whether the other person would tell a lie or the truth if given a gold coin. You just need to take what he says and consider the opposite. The same applies in reverse, and the result is the same.
