1, ancient times: postal delivery system, Hongyan delivered books.
2. Modern: telegraph and network communication.
As far as the communication history of mankind is concerned, the evolution of information communication mode presents such a vein: visual culture, auditory culture (intuitive feeling, "spirit of seeing")-conceptual culture ("spirit of reading")-new audio-visual culture ("new spirit of seeing").
Therefore, we absolutely have reason to believe that in the future, image information will occupy the mainstream, and literature will retreat to an extremely marginal position and be replaced by an audible, visible and even tangible multimedia art. However, words will not be completely replaced by images as predicted by some people, because words are the main means to accumulate knowledge, an indispensable link for human beings to acquire abstract thinking and an indispensable medium for human communication.

Hongyan delivers books. The geese are messengers.
. The story of Hongyan's biography originated from Hanshu? Su Wu biography, emperor wudi, Su Wu to the huns, detained in the north sea. Later, Korea and Hungary reconciled, and Korea begged Su Wu and others to release them. Xiongnu lied that Su Wu was dead, and Chang Hui, a subordinate official of Su Wu, met an ambassador in the evening, and told him to tell Xiongnu that when Emperor Wu of the Han Dynasty was hunting in the forest, he would come from the north to see Hongyan, whose feet were tied with silk, saying that Su Wu and others were trapped in a certain jersey. Khan was frightened when he heard the news, so he had to put it back in Su Wu. As a result, later generations will associate letters with wild geese, and geese, as messengers of letters, often appear in the poems of literati. For example, "the geese come without evidence, and the road is difficult to dream." (Five generations? Li Yu's "Qing Ping Le") "Fish book is not without geese, and I want to make sad autumn poems." (Sword by Li Mingxian) Not only that, when the ancients mailed letters, they also made them into the shape of geese with bamboo or silk in the middle, which was convenient for mailing. The ancients also used Hong Jing to refer to beautiful women. Cao Zhi described Luo Shen in "Luo Shen Fu": "If you are surprised, you will look like Youlong". Shan Li's Note: "Dancing is like a wild goose's surprise". "The spring waves under the sad bridge are green, which was once a stunning photo" (Two Poems of Shenyuan by Lu You in the Southern Song Dynasty). Here, it is used to describe the beauty of Lu You's ex-wife Tang.
