The sun and the moon shuttle, day and night alternate. When the sages of Athens shouted "I love my teacher and I especially love the truth," Confucius was concentrating on his work and talking about the righteousness of the Spring and Autumn Annals; hundreds of years later, the wise men with solemn treasures pinched flowers and remained silent, while Zhang Qian and Xuanzang from the East cleared the Western Regions; when Magellan led the fleet to set sail, the Ming Dynasty fleet lowered its last sail. This planet has given birth to countless civilizations and witnessed the rise and demise of countless countries. But from the macro perspective of the universe, all of this is just like a child's play house.
