Use Value is a project in form of commerce initiated by Chang Yuchen in 2016. Use Value produces hand-labored useful commodities. Use Value believes art exists not only in museums but also in the mundane gestures of everyday life. Use Value measures artist's labor by the common rules of economic reality. The price of each product, the exchange value, is calculated by the average of all hitherto existing hourly rates that Yuchen has earned, multiplied by how many hours she has spent on this product, in addition to the cost of raw materials.
