Compared with modern letters, the letters in ancient books are often short, but short, pithy and meaningful. This is because in ancient times, paper resources were relatively scarce, and most people could only express information in a very simple way, while the ancients preferred to express their feelings by metaphors, symbols and other methods. Modern letters pay more attention to the description of details, facts and nuanced expressions.
Although great changes have taken place in the way people communicate in modern society, the spirit of faith represented by letters in ancient books still has far-reaching significance. In order to maintain ancient beliefs, we need to do two things: first, maintain honesty and credibility, and establish a social environment of mutual trust and respect; Secondly, some metaphors and symbols are used to express emotions in communication, which makes communication more meaningful and deep. Only in this way can we truly understand the profound connotation represented by letters in ancient books.
