What did the ancients call the sky?

God, sky, sky, sky, sky, sky, sky, sky, sky, sky, sky, sky, sky, sky, sky, sky, sky, sky, sky, sky, sky and so on.

The sky is an important part of the earth. In ancient China, there was a saying that the sky is round and the place is round.

1. It means the sky is wide. Tang Shen's poem "Long Shao Temple": "The clouds cover the wood and the sky sees the rattan board." Former Shu Guan revised the poem "Sending Monks to Tiantai Temple", saying, "Heaven smells holy and clear, and the waterfall becomes a towel."

2. The vast space listed by the sun, the moon and the stars. Tang Hanyu's poem "Nanshan": "The sky is full of eyebrows, and the thick green painting is new." Mao Dun's Autumn Harvest: "At dusk, there are occasionally a few white clouds in the sky, and the whole village cheers."

People can observe meteorological or astronomical phenomena in the sky, so as to know the change of weather, the passage of time or their position. You can know the time of day at sunrise and sunset, and the moon's profit and loss for a month at night. The big dipper can indicate the north. The thickness and shape of clouds can judge whether it will rain or not. You can enjoy many beautiful phenomena in the sky, such as rainbow, aurora and meteor shower. Birds can fly in the sky. Due to the increasing use of fossil fuels such as oil, especially fuels such as coal that will release sulfur dioxide after burning, the visibility of the sky is gradually decreasing from 1973, except in Europe.
