Abstract: LRJS Painting Manual or Painting Manual of Tang Bohu（Liu Ru Ju Shi)is a compilation of painting theories and techniques that appeared in the middle and late period of Ming Dynasty. Ever since the Qing Dynasty, the book has been recorded in various collection catalogues, and it has also been widely cited as important reference material in manytheoretical works on the art of painting. Even so, most scholars still believe that a talented Bohemian artist like Tang Yin should have disdained to compile such a rudimentary manual. Therefore, LRJS Painting Manual is almost certainly a pseudograph published in the name of Tang Yin. However, so far no scholar has made a firm argument on the authenticity of the book. In view of this situation, this paper will discuss the authenticity of LRJS Painting Manual by exploring the relationship between LRJS Painting Manual and another painting manual bookpublished in the Ming Dynasty entitled Master Du’s Four Manual Books·Manual of Painting in a concurrent attempt to reconstruct the publication history of LRJS Painting Manual.

Key words: LRIS Painting Mamal, Master Du’s four Manyal Books, publication history.
