求翻译：可以取得第一手的知识。我们在广播电视、书籍报刊中得到的信息都是第二手的，都是通过别人的眼睛、戴着别人的有色眼镜来看世界，只有亲身实地，才能有最真实的感受。是什么意思？

You can obtain first-hand knowledge. In broadcast television, print media, we obtained information was second hand all through the eyes of others, wearing tinted glasses to see the world from others, only in-person on the ground, to have real feelings.
