This picture book tells the story of Monkey fighing a demon taken from the Chinese mythology or folk story called The Pilgramage to the West, which features Monkey, Pigsy and Sandy who accompany a monk on his quest for Buddhist texts.  There are 23 pages of beautiful full-color illustrations by Chang Hung-tsan with just a few sentences of text.  I purchased the book in Hong Kong in the 1980s, where it was published and printed.  It measures 9.75" wide x 10.25" high.
