last one is: an english and chinese dictionary, a "revised version" of william lobscheid's dictionary, printed in 1883, in tokio.
the appendix is the gem, from page 1227-1373. which has bilingual texts ranged from trimetrical classic (三字經), wisdom verses, merits, thousands of famous phrases and proverbs; and miscellaneous "common knowledges" of the days of yore. all in literary chinese and english.
samples:
有利必興.有害必除 ⋯ "what is profitable must be put into action, what is injurious must be removed"
有緣千里能相會.無緣對面不相逢 ⋯ "no distance can separate what heaven unites, or unite what heaven separates"
月明月明不可獨行.寔要獨行手提紅燈 ⋯ "bright moon, bright moon, but don't walk alone; if you must walk alone, take a red lantern in your hand"
anyone who want a genuine "chinese proverb", have a read of these books, particularly the last one.
or, anyone who want to "fake" one, study these thoroughly.
