At an exit of a subway station in Chengdu, a wall has been repainted and rows of hooks have been installed, where passers-by can hang warm clothes they donate to those in need.

The idea of the wall was developed in Iran. Because of the cold current and economic crisis in 2015, the number of homeless people soared in Iran. Many people got their clothes through the “Wall of Kindness”. (Photo/Chinanews.com)
