Personal opinion on the date of first printing of Jing yue quan shu (Jingyue's Complete Book).

Generally, the date of the first printing is based on the description, "Introduction to the Complete Book", in the postscript written by his grandson Lin Riwei, saying that "in the year of Gengchen (1) brought (my draft) to eastern Guangdong to tell the Fangbo master Lu... (who) donated his salary for the printing which lasted for several months". By Fangbo, it is another name for the position of Buzhengsi (Provincial administrative commissioner). Here, it refers to Lu Chao, by then the commissioner of Guangdong. In the Chronicle of Qing Officials, it is recorded that Lu Chao was in charge of Guangdong provincial commissioner in the year 37-40 of Kangxi reign (1688-1671). Together with other reference data, I draw the conclusion that Jingyue's Complete Book should be first printed in the year 1700.
