(October 13, 1949)
Your advocacy of shifting from the paper-trading business to the paper-manufacturing industry, as well as your efforts to improve native paper and expand its applications, are all commendable. I am grateful that you have used this native paper to copy several of my articles. Now I have written a few words for you, but please do not use them as an advertisement.
