Irises bloom every April and May. They bloom only once a year, and each flower only blooms for one day. A flower often blooms in the morning and withers in the evening. The ephemerality and beauty of the iris amaze and amaze the world. She is Ning Yuan, a noble and beautiful princess from Chang'an. In the eyes of the world, her life was as short and beautiful as an iris. ... As her years progressed, she would always think of Luoyang when she was young, far away from the rivers and lakes, free and happy in life. She will also always think of Chang'an at that time, high in the temple, ten feet red, prosperous and romantic, but with swords and blood, flesh and blood... There is a Chang'an flower that she can't see endlessly in her lifetime.
