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.",More than seven hundred years ago, Ye Li Rongren was a brilliant mind. At that time, when Emperor Yuanhao proclaimed himself emperor, Western Xia still used Chinese characters. Yuanhao had grand ambitions and wanted to make his mark, so he ordered the minister Ye Li Rongren to create a writing system unique to Western Xia.。
