The sun took the last trace of afterglow, and we are still struggling to ride. At this time, the Xi'an Hua Deng was at the beginning, and history and modernity were intertwined here. I seem to be going through time and space in the next second, dreaming back to the prosperous Tang, raising my hands and feet, and picking up the heroic and historical qualities. Xi'an City Wall witnessed the rise and fall of Chang'an for thousands of years, and has penetrated into the bones of every Xi'an people since ancient times. Xi'an people flowed from birth and flowed with the blood of history. When they grew up, the square city accompanied them. Spend the day and night.
