Use Value, a brand which produces handmade useful commodities, was founded by Chang Yuchen in 2016. Here, the labor of hands is measured with money, the act of possessing is considered love. 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 hourly rate of all hitherto hourly rates that Yuchen has earned, multiplied by how many hours she has spent on this product, in addition to the cost of the raw materials.
使用价值是常羽辰于2016年在纽约成立的手制品牌，在这里，双手的劳动被换算为金钱，购买与占有被看作是爱。使用价值相信艺术不只存在于美术馆或画廊，也存在于日常生活中的举手投足；使用价值用社会经济的普遍标准去衡量艺术家的劳动。每一件产品的价格，即交换价值，是由以下公式计算得出：常羽辰至今所有打工时薪的平均值 X 常羽辰制作这件产品所花费小时数 + 原材料的开销。
