After playing for a few days, I went back to see that Ba Tou was still studying the sheepskin map, so I asked: "Ba Tou, you've written so much on your paper, what have you figured out",I shook my head and piled up ten or so sheets of white paper. "Too difficult," I said. "The day before yesterday, I went to the Yin Chuan Museum and copied a character from a sheepskin scroll. I asked a deputy researcher for help, but... he didn't recognize it either.",I was originally going to ask Guide Lao Zhang to come along, but he said it wasn't necessary. He should remember the route well enough, and the Hutu people are waiting for us too, so they probably won't be moving anytime soon.。
