Sitting blankly in the carriage, I gazed at the poplar trees outside the window slowly retreating. I wonder what the distant grassland looks like at this moment. Behind me, under the sunset, lies the ancient path, and the imperial city at the end of the ancient road is getting further and further away from me. Can I come back? The sound of hooves echoes, my heart feels boundless. Looking back, I find for the first time that the palace under the sunset is so beautiful. But now, I no longer belong to it.
