一个人走在冬夜的旷野里,大雪纷飞,看不清四周的道路。他一直按自己认为正确的方向前行,但很快就不知不觉地偏离了预定的路线,结果又同到了原处。有人划船,想穿过3千米的海面,四周漆黑一片,并且浓雾弥漫。划了一段时间以后,他上岸了,却发现这就是他出发的地 A man walks in the wilderness of winter nights, and the snow is falling in the sky, and he cannot see the roads around him. He has been moving in the direction he thinks is correct, but soon he unknowingly deviated from the intended route, and the result is in the same place. Some people boated and wanted to pass through the 3 km of the sea. They were all dark and covered with dense fog. After drawing for a while, he landed, but found that this was where he started.
