Most of them believe that Norwegian visited the "New World" long before Columbus did, so westerners feel this may be a false celebration. Experts have found tools, camp sites, etc., to back up the claims that the Norwegians came first. Also, a British sea captain, Gavin Menzies, has written a book, 1421, the Year the Chinese Discovered America, in which he cites the evidence that Chinese fleets sailed along the Pacific coast of North America some 70 years before Columbus landed on the Atlantic coast of America. Maps of the Chinese voyage show this to be factual. 大多数人认为挪威人远比哥伦布早到达“新世界”,因此西方人觉得也许他们一直在错误的庆祝。专家已经找到了工具和野营遗址等等,来支持挪威人是最先到达美洲的这一声明。同样,一个英国海航家,写了一本书,在1421年中国人发现了美洲,在书中他引用了中国舰队先于哥伦布登陆美洲大概70年沿着北美洲航行的证据。中国人的航海地图证明了这个是真实的。
