There is a flower shop hidden in the deep alley of the old city, open only to those who are destined. Chu's poetry uses flowers as a guide, and uses flower stories to explain people's obsessions - either waiting during the Republic of China, or feeling lost in ancient times. Every flower hides a piece of the past, and every visitor brings a piece of their mind. The return of the flower spirit is also the time when the knot in the heart is untied.
