Beijing, January 7 (Youth.cn) - On January 6, 2026, 22 trees by the Jianbo Bridge in Xiaoshan District, Hangzhou, were adorned with hand-knitted “sweaters”, adding a touch of warmth and vibrant color to the bleak winter. The unique creative landscape not only brightens the winter scenery but also raises public awareness of the importance of cherishing and protecting nature. Photo/CFP
