凸 means 'convex'

This essay collection about hilly topography focuses in part on the physical world: bumpy surfaces, volcanic cones, lens curvature, embossed paper, and especially flat abs! But such topics are also rich in figurative possibilities. One essay first examines objects that stand apart from the rest, then demonstrates how being separated from the main action affords a clear vantage point. That essay also touches on unrequited love. Another illuminates how it feels to be overwhelmed and slightly depressed. A third addresses the ups and downs of life. Uneven ground proves to be fertile!
