小的时候,不知道世界有多大,没敢想过出国的事。到了青年时代,因工作性质,我是搞航空摄影专业的,几乎走遍了中国。对世界也有一定的了解,那时个人经济条件有限,更重要的是,那时中国还是以“阶级斗争”为纲,国家闭关自守,没人敢出国。到了改革开放时代,国家强盛了,中国在世界崛起,很多人开始走出国门:留学、探亲、考察、旅游。很多海外工程遍布世界各大洲。进入21世纪,中国的普通百姓也出国旅游了。 Small, do not know how big the world, did not dare to think about going abroad. In the youth, because of the nature of work, I was engaged in aerial photography and traveled almost all over China. There is also a certain understanding of the world. At that time, the personal economic conditions were limited. More importantly, at that time, China still used “class struggle” as the key link and the country was self-reliant and no one dared to go abroad. By the time of the reform and opening up, the country was strong and China rose in the world. Many people started to go abroad to study abroad, visit relatives, study tours, and travel. Many overseas projects spread all over the world. Into the 21st century, ordinary people in China also travel abroad.
