Kayla Chan, 25, poses for a photograph at Victoria Park, in Hong Kong, China, May 4, 2021. "As a permanent resident of Hong Kong, I suppose I have the right to walk on the streets freely. When you put water barriers and the road is not under construction, I have to avoid it without a reasonable explanation of what's going on. If I touch the water barrier, will I be stopped and searched? When I see them, I feel highly alert and I feel like it is a high-risk place. The water barriers are an extension of the oppression of critical voices by the state apparatus. Although social movements are dead in Hong Kong now, the water barriers and the mesh wires are still here to remind us of what happened and the unresolved problems."
