Many countries have different ideas about different animals, but when we talk about pigs, we may have the same idea of them--the pigs are ugly, lazy and stupid(愚蠢的).
Just look at the idioms in Chinese. We have "Boiling a dead pig" and "A pig looking in the mirror is still a pig". And in English, they have "earing like a pig" and "sweating like a pig". None of them are good.
In fact, there are some good things about pigs. First, pigs are not stupid . Their IQ(智商)is like dogs and chimpanzees(黑猩猩). They can remember things for a long time. And some pigs can learn things from people. Second, pigs are very clean animals. On farms, they live in dirty places, so they are very dirty. In the wild (野外), pigs are very clean. Third, pigs are very friendly animals. ▲ . Of course, people keep the small kind, not the big kind. Small pigs are very cute.
There are cute pigs in cartoons, too. Peppa Pig, for example, a UK cartoon, becomes popular in many countries. The four pigs in the cartoon teach children about love, friendship and family. In China, we have McDull, a pig who works hard to make his dream come true.
