After the autumnal equinox, the streets of Keqiao turn into a colored oil painting. Featuring green leaves, yellow flowers and pink fruits, the Koelreuteria paniculata rich in colors are a messenger of autumn. Never contending in spring or summer, the Koelreuteria paniculata leave the beauty to the color autumn.

Standing on both sides of Keyan Avenue in Keyan District, you can see a wonderful picture scroll composed of golden flowers, or pink or red fruits and green leaves of the Koelreuteria paniculata in a distance, and feel how beautiful autumn is.
