对外开放是现代中国改革的一项伟大举措，由此带来的辉煌成就有目共睹。然而，早在千年以前的唐朝时代，我们的祖先就已经把国门向世界打开，对内引入域外文明，对外弘扬盛唐文化，显示出古代中国人的博大襟怀和高度自信。可惜，有关这一段精彩的历史却一直没有人去系统地... Opening up to the outside world is a great move for the reform of modern China. The brilliant achievements made by it are obvious to all. However, as early as the Tang dynasty a thousand years ago, our ancestors had already opened their doors to the outside world, introduced extraterritorial civilizations internally and carried forward the prosperity of the Tang culture to the outside world. This shows the broad-mindedness and high confidence of the ancient Chinese people. Unfortunately, no one has systematically been involved in this wonderful history.
