What else did the ancients call letters?

Ancient people called extra-cursory books leisure books mainly because these books were not professional books but works in literature, history, philosophy, and other fields. They were usually not practical but focused more on spiritual enjoyment and inspiration, so they were called leisure books. In addition, in ancient society, people were usually busy with their daily work and reading extra-cursory books became a way to relax and relieve stress, so it was also regarded as a kind of "leisure".

The way the ancient people communicated was different from modern times, but there were also some similarities. In ancient China, people often used oral language to communicate. In ancient times, people often used poetry, prose, Fu and other literary works to express their thoughts and feelings. These works were the models of ancient dialogue and communication. In ancient times, people would also use some written language to communicate. For example, many of the conversations in The Analects of Confucius were expressed in written language. In addition, the ancient people would also use some specific ways of dialogue to communicate. For example, in the palace, officials would use the official language to talk. This official language was called "Jing dialect". The way the ancient people communicated was quite special, but there were also some places that we could learn from. By studying the ways of communication in ancient times, we can better understand ancient culture and ideas.

The ancients used mandarin ducks, wild geese, lovebirds, connected branches, and lotus flowers to symbolize lovers. Mandarin ducks were used as a metaphor for husband and wife. It was first used by the Tang Dynasty poet Lu Zhaolin's poem "Chang 'an Ancient Meaning", which praised the beautiful love. Wild geese were regarded as a symbol of loyalty. In ancient times, wild geese were often used as betrothal gifts to express their feelings. The lovebirds were the names of birds in ancient Chinese legends. They were often used to describe loving couples. A connected branch referred to a plant that had the branches of two trees growing together. It was called an lovesick tree or a couple tree. It was a metaphor for the love between husband and wife. The twin lotuses were seen as auspicious and festive signs, and were also used to symbolize the lingering love between men and women.

The phrase "how many people returned from the ancient wars" meant how many people returned alive from the ancient wars. This sentence came from the "Liangzhou Ci" by the Tang Dynasty poet Wang Han. It expressed the hardships and dangers of war, as well as the determination and sacrifice of the conquerors in the face of life and death. A campaign referred to going to the battlefield to fight, while the phrase "a few people returning" implied that there were very few survivors in the campaign. This sentence expressed the loyalty and sacrifice of the soldiers to the country and the people through passionate words. At the same time, it also inspired people to have a sense of hardship in reality.

Whether the ancient people really cultivated immortality was a controversial issue in real life. Although there were records of cultivation in ancient literature, these records were often described in myths and legends or literary works. We can see some recommendations for ancient cultivation novels, such as "Ethereal Journey,""Tai Hao,""Adventures in the Immortal Martial World," and so on. These novels were fictional works, describing the story of the protagonist starting to cultivate from a mortal. However, these novels could not be used as evidence to prove that ancient people really cultivated immortality. Therefore, it was impossible to determine if the ancient people really cultivated immortality.

Yes. Ancient Greeks had works that can be considered early forms of science fiction.
