Countless words have been used by Chinese writers and poets to describe the beauty of autumn in Beijing.
The novelist Shi Tiesheng wrote about the daisies in Beihai Park; writer, essayist, poet and literary critic Lu Xun was inspired by the full moon near the Forbidden City; writer and translator San Mao described drinking beer and boating on Houhai Lake; while novelist and short story writer Mo Yan has written about clouds and birds seen in hutong (alleyways).
As China's capital, Beijing has deep cultural traditions, while also being home to advanced technology and modern facilities.
Its residents and visitors now have many more areas in which to enjoy blue-sky autumn days than they did in the past.
Zhang said: "After years of effort, we now have colorful plants in three seasons－spring, summer and autumn. In 10 to 20 years, Beijing will have colorful plants for the whole year. It's our job to make life more colorful for everyone in this city."
