Two doors, one is the door of birth, and when you enter, you are born. One is the dead door, if you go in, you will die. There are two doormen in front of the door. One can only tell the truth, and the other can only tell lies. If there is only one question, you can't tell which one is lying, but you can be sure that you are born. Ask any janitor and ask, "If I ask another person how to get to the door of life, which way will he point?"

If you ask an honest man who knows that another person will lie, he will show you the direction of the death gate. If you ask a liar, he knows that another person will point to the door of life, but he must lie, so he will also point to the door of death. In short, it refers to the door of death, don't choose.
