This is a ready-to-frame Giclée print of the Wuwei (without action) characters in Chinese and old Korean Hanja.
無為 or “Wu Wei” is a Daoist (Taoist) tenet that speaks to the idea of letting nature take its course.
Some will say it's about knowing when to take action and when not to. In reality, it's more about not going against the flow. What will happen is controlled by the Dao (Tao), for which one who follows the Dao will not resist or struggle against.
