Three mascots (吉祥物) welcoming everyone to join in the event. They are known as “Memories of Jiangnan”, and it’s from a famous line by Tang Dynasty poet, Bai Juyi: “When I recall Jiangnan, Hangzhou brings back most of my memories.” Here is some information about these three robot mascots.
Congcong
| It is a yellow robot. Its name is from the Cong jade pendant of the Archaeological Ruins of Liangzhu City (良渚古城遗址出土的玉琮). It stands as a symbol of China’s 5000-year-old history. It’s also a symbol of the earth and harvest. |
Lianlian
| It takes green as its main color. It is a reflection of West Lake (西湖). As a symbol of life and nature, its name is from the green leaves in the lake. |
Chenchen
| It’s blue. And it characterizes the Beijing-Hangzhou Grand Canal (京杭大运河). Its name is from the Gongchen Bridge, with a history of over 400 years. It’s a symbol of science and technology. |
