Professor Cheng Man Ching's Sage's Principle

Professor M.C. Cheng had left an unfinished book in my hands before his final trip to Taiwan.  I began to proceed on the final translation in 2013 with the help of Dr. Stephen Cowan.  It needs supplementary material to be housed with the book.  A container for both is specifically designed by a renowned designer, Daniel Kelm.  I would like to use Go Fund Me to raise $2000 to cover his expenses.  Thank you.
