Proof: In the mountains (some versions are "caves"), China's day (some versions are "one day") has been in the world for thousands of years. Tell the story of "Loukeshan" in Chinese. It is said that a woodcutter went into the mountain to cut wood, and when he saw two immortals playing chess, he forgot the time. When he finished, he found that his axe handle had rotted.

It has been seven days in the cave and a thousand years on earth. What I said is as follows, and I will quote them from different sources:

In the Eastern Jin Dynasty (345-356), Yu wrote: "There are stone chambers in Xin 'an Mountain, so you can enter them. I saw two boys playing chess. Before the end of the game, depending on the fact that his salary was cut and rotten, he came back again and the village was gone. "In a few words, explain the people, things and causes and effects clearly. Concise words contain rich meanings, which make people memorable and reverie. According to the records, the Book of Jin has such a brief record: "Go into the mountains and see the two children." Sit and watch, and the axe will rot when you get up. "

According to Einstein's theory of relativity, time slows down at the speed of light. The so-called sky must be an aircraft flying at the speed of light or sublight.
