Benches, columns, handrails and trees in the Shanghai Fashion Center put on colorful sweaters as the temperature in Shanghai drops on December 12, 2020. These sweaters are mainly knitted by a group of compassionate moms in the Shanghai Textiles Museum, and some are collected from volunteers in society. /CFP

Enthusiastic participants spend months of their spare time knitting colorful wool works in creative patterns, decorating and warming the center. The sweaters, made of thicker wool that is warm to touch, keep visitors away from the chilliness. /CFP

Putting on colorful sweaters is one of the activities in Shanghai Fashion Center to welcome New Year. The upcoming year of 2021 marks the 100th anniversary of the old factory where the center was built. There will be more celebration activities by then. /CFP
