Guangzhou and Shenzhen install cement spikes under overpasses to guard against the homeless
Recently, new “landscaping” has appeared under the overpasses in Guangzhou and Shenzhen, featuring a lot of individual pyramid-shaped pointy-little pieces of cement covering the entire overpass floor. Some netizens say this was done by chengguan to guard against homeless sleeping under the overpasses and affecting the appearance/image of the city, but the city management officials deny this.
