Traveling Across Time and Space Can Save the Day

As we all know, the sky is high enough for birds to fly, and the sea is wide enough for fish to jump. Think about it, this is also the case. If fish don't jump, they don't know the width of the sea. Tigers don't run. They don't know the vastness of the earth. Birds don't fly. They don't know how high the sky is. We are like octopuses setting limits for ourselves, or spying on the world like a mayfly. It's better to be there, see clearly, and then return to the starting point. Will the answers be the same...
