In the spring of 1991, at a time when my dialect “Linfen Dialect” came out, I received a letter from Professor Wang Futang, a Chinese professor at Peking University. The letter said that one of his Japanese students thought of investigating Linfen dialect in Shanxi Province. Mr. Wang hoped that I could instruct the student to do fieldwork and I gladly agreed. The Japanese PhD student is the author of this book, Tetsuya Ichiro.  mouth monarch attack Chinese dialect and phonology, its own Chinese table?
