Short stories of ancient people transmitting information (some failed) and short stories of modern people transmitting information (some were good).

The first story (homing pigeon, monkey with letter)

In Bekasa, Nigeria, people use monkeys to deliver letters. People keep the mother monkey and the son monkey in two places, and often take the mother monkey to find the son monkey, so that the mother monkey can know the route. When people need to communicate, they put the letter in a bamboo tube and tie it to the mother monkey, so that she can go out and look for the baby monkey. The mother monkey can always deliver the letter to the destination. Carrier pigeons have been an effective information transmission tool since ancient times. In today's highly developed communication technology, homing pigeons still have their own place. In war, communication is very important. However, once a nuclear war breaks out, the strong electromagnetic radiation generated by the nuclear explosion will paralyze all kinds of existing electronic communication systems, but homing pigeons can still fly freely. The Swiss army trained and bred homing pigeons that can throw books in two directions. These homing pigeons no longer transmit traditional letters, but carry computer chips in capsules, and the password information can only be read on special equipment, which is extremely confidential. Carrier pigeons may even become special signalmen.

The second short story (The Legend of the Hongyan) It is reported that in the first year of Emperor Wu's reign (BC 100), Su Wu, the ambassador of the Han Dynasty, was detained by the Xiongnu monarch Khan. He refused to submit, so Khan exiled him to the no-man's land in Beihai (now Lake Baikal) to shepherd sheep. 19 years later, Zhao Han succeeded to the throne, and the two countries reconciled and got married. The envoys of the Han Dynasty came to Hungary to ask Su Wu to return to China. Khan refused, but he couldn't say it, so he lied that Su Wu was dead. Later, Emperor Zhao of the Han Dynasty sent envoys to Xiongnu, and Chang Hui, the detained deputy envoy who sent envoys to Xiongnu with Su Wu, met with the envoys of the Han Dynasty in secret one night with the help of the jailer, told them about Su Wu, and came up with a plan for them to tell Khan: "When Emperor Wu of the Han Dynasty was hunting in Shanglinyuan, he killed a goose with a letter tied to his foot, which said that Su Wu. Han was very happy after hearing this, so he blamed Khan according to Chang Hui's words. Khan was greatly surprised after hearing this, but he couldn't deny it, so he had to let Su Wu go back. Therefore, Su Wu is regarded as the most virtuous diplomat in the history of China, and The Legend of Hongyan was once regarded as a beautiful talk. This virtual wild goose has since become the embryonic form of China Post's sign of spreading its wings.
