Spikes Under Chinese Overpasses To Prevent Sleeping Homeless?

From NetEase:

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.

July 1 evening, under elevated airport highway’s Huangshi entrance, over a hundred square meters of flat cement ground has been covered with cement spikes.

American homeless not only get free food provided for them every day, there are even volunteers who regularly come give them medical checkups.
If a certain country [China] keeps cracking down on the homeless, the homeless will end up having to go to public places to sleep.

One shouldn’t go too far…

Why not just bury/plant landmines?

Affecting the city’s appearance/image? Unbelievable! You bastards.

I seem to see a bunch of graves for government officials.

印小兄 [网易浙江省杭州市网友]：

Looks like a bunch of small graves.

Chengguan, this is inexcusably wrong! This is inhuman!!

网易江苏省常州市网友：

This is you forcing people to cause trouble.

网易广西南宁市网友：

[Can the government please] use taxpayers’ money to do something meaningful!

How a country treats its women, children, and disadvantaged determines how civilize that country is. This time, China has once again made us feel ashamed.

You guys doing this is basically forcing these people who have no way out to rise up!!! Why not build some homeless shelters! If they had a place to go, would they still go under the overpasses!? Are you guys fit to be the people’s public servants!? If we ordinary common people truly were the masters [of the country], public servants like you guys would’ve died a hundred times already!!!

操蛋宫乌猿 [网易山东省潍坊市网友]：

Instead of thinking about how to provide a better social security/safety net system, you guys spend all day thinking up these lousy ideas, just how did I end up electing you guys?

What guarding against homeless? It must be to prevent people from parking there. There must be a paid parking lot nearby.
