"Many people have helped out, from a granny in her 70s or 80s to security staff and other members of the community. They are all participating enthusiastically," said Hong, who was inspired to launch the wall by the charity work she saw on a recent visit to the United States.

"Warmth and love are needed by everyone. It is just a simple wall, but it allows anyone to donate their spare clothes and those who are in need can take them."

In 2014, a South African named Max Pazak came up with the idea of a pop-up clothing swap shop that made it easier for people to donate and more dignified to receive.
