What kind of pigsty is the most practical in rural areas?

The shed circle is better! That is, a cement brick ring with a height of 1.3m, a cement pile with a height of four feet 1.8m, and two cement piles with a height of 2.2m in the middle of the wall are connected by Vitex negundo and fixed by asbestos tiles. In winter, add a layer of plastic paper and two layers of grass felt on the sides and top, so that there will be no problems in winter and summer! Of course, the height of the cement pile can be determined according to your own situation!
