Find a bronze dictionary.

Jin Wen Bian by Zhonghua Book Company and Wen Gu Lei Bian by Shanghai Ancient Books Publishing House can both be used as Jin Wen dictionaries. Both are 16, big and thick. When I visited the bookstore recently, I saw the above two kinds of 32-inch miniature books (also available in online bookstores), which are very small, only one-sixth of the original big books. Suspected piracy. However, after a cursory look, I found that the two books are clearly printed, with edition notes, prefaces and dictionaries, and the fonts are not too small. If it is pirated, it is also genuine, so there is no typo problem, as long as there are no missing or wrong pages.
