A Tai Chi patterned microsphere‐cavity array on a flexible quantum dot film to enhance and direct white‐light emission is demonstrated here. Two aspects of a material, i.e. rigidity and flexibility, are implied by the symbol. The microsphere cavity is rigid with stable optical properties, while the microsphere array is flexible due to the weak connection between the microspheres. The cover image, referring to article number 1901228 by Yinzhou Yan and co‐workers, combines Chinese traditional culture with modern science to motivate new ideas in flexible nanophotonics.
