Where is the valley of forgetfulness? Specific point

Hello, I'm glad to answer your question, forget the sorrow Valley. There are two ways. The first way is to drive a rickshaw in a city in your own country. At the bottom, there is a valley that delivers to forget the sorrow. Or you can go to Xanadu from the border of your own country. When you press the M key, it will be displayed on the map. I don't know exactly where to go, because I usually do.
