In the Zhengde period of the Ming Dynasty, there was a businessman surnamed Du in Shanxi. He had a rich family and a son was born dumb. Therefore, it was named “Yiming” mainly because of its amazing meaning. At the same time, it also had a great expectation of making a great success. Although he was speechless, he was still able to see and hear, and his comprehension was very high. Du Laoyan asked the teacher to teach him how to read. He kept his eyes on it. He could write it silently every day. His teacher was very surprised and regarded him as a child prodigy.
