Li Shangyin's "Untitled" "Pengshan has no more roads to go here, and the blue bird is attentive to visit." “
Cui Guofu's "Qixi" "Thinking of Emperor Wu of Han from afar, when did the blue bird pass".
Evidence of "Yellow Dog Biography"】

Tang Dynasty. Fang Xuanling et al. wrote the Book of Jin. Lu Ji Biography: "(Lu) Ji has a steed dog, known as 'Yellow Ear'. Even though he was confined to the Beijing Master, he had no home for a long time. Laughing Dog said: "There are no letters in my family, and Ru Nengzhen (jī, send) books to pick up news is not it?" The dog wagged its tail. The machine is a book, and it is held in a bamboo tube and tied around its neck. The dog searched for a way south, and then went to his home, and got to repay Nailuo. This means that the Western Jin Dynasty literary scholar Lu Ji was an official in Luoyang, thousands of miles away from home, and it was difficult to hear from him. One day, Lu Ji was missing his hometown, so he casually said to the yellow dog next to him, "Can you help me pass on the message?" The yellow dog even wagged its tail in agreement. Although surprised, Lu Ji still tied the letter to the yellow dog's neck and let it go. As a result, twenty days later, the letter was successfully sent out, and the home hot reply was also brought back. He will always send him letters. Later, the yellow dog became a messenger. Later, it was often called "Yellow Dog Book", "Yellow Dog Sound" and so on.
【Evidence of the "Carp Book"】
Before the invention of paper, the ancients often used about a foot of white silk to write letters, called "ruler", so the letter is also called "ruler book". The ancients also wrote letters on bamboo or wood chips. Because the bamboo pieces are called "Jane" and the wood chips are called "Za" or "Mu", the letters are also called "Shu Jian", "Shu Za", "Shu Mu", "Jian Za", "Jian Mu". The length of the "Jianzha" is the same as that of plain silk, and it is taken by one foot, so the letters are also called: "ruler", "ruler", "ruler book". For example, Bai Juyi: "In the daytime, Xu Fang came to the door and held a ruler in the countryside." Cen Shanshi: "It is difficult to meet in lovesickness, and when you show the ruler book, you can read it." ”
The "Carp Biography" canonizes the Han Dynasty Lefu folk song "Drinking Horse Great Wall Cave Line" "The guest came from afar and left me a double carp." Hu'er cooks carp, and there is a ruler book. "Because of this folk song of cooking fish and getting a book, the story of the carp book was laid out. According to legend, ge Xuan, a Wu of the Three Kingdoms, returned letters from Hebo and made the carp a messenger. The poem of the Tang poet Meng Haoran also said very clearly: "If the ruler book is not stingy, it is also hoped that the carp will be passed on." ”
In The Tang Dynasty Wang Changling's "Solo Swim", "holding a double carp in his hand, watching a thousand-mile goose." The "double carp" mentioned here is not really two carps, but a letter shaped like a carp, which is used here to refer to it as a letter. Li Shangyin's "Sending Orders to Fox Langzhong" "Song Yun Qin Shu has been away from home for a long time, and the double carp has a paper book". The "double carp" here also refers to the letter. In the Tang Dynasty, since the Zhenguan period, letters were made of thick cocoon paper, shaped like carp, with scales painted on both sides, and books could be stored in the abdomen, known as "carp letter".

Shan Yu heard the words, and was shocked to see the left and right, so he had to apologize to the Han envoy.
Tang Ren de you has a poem: "The master rides a thousand horses far to the east, only hopes that Hengyang Yanzu Book." Song Dynasty Qin Guan's "Ruan Lang Gui Xiangtian Wind and Rain Break the Cold Beginning" "Hengyang still has geese to pass on the book, Chenyang and Yan wu." It's all the story of "The Book of The Wild Goose". According to legend, Hengyang has returned to Yanfeng, and when the geese arrive, they return.
