When you open this book, you step into a river flowing backward.
What the fingertips touch will not only be the page, but the cold rain at night in Chang'an, the roughness of the wind and sand outside the Great Wall, or the long night with beating heart before a certain palace change. Here, you will temporarily put aside your own identity and gaze at the starry sky of the prosperous Tang Dynasty with another pair of eyes - the stars that are so brilliant may also be about to collapse.
History is not a specimen viewed from afar. Please try to let his blood rush in your veins, and use her determination to face difficulties you have never experienced before. Every breath, hesitation, ecstasy or heartache is a copy of life that you cannot receive in your own time.
Rather than providing answers, these words hand over a key. When you close the page, what you bring back is not a piece of knowledge, but a weight of life - as if you have quietly relived your life in the gap of time.
