Toads don't bite. Toad lay on his feet. Toad is a frog, an amphibian, ugly, covered with acne and covered with mucus, which makes people feel sick at first sight, that is to say, toad doesn't bite or hurt people, so this two-part allegorical saying came into being.

Brief introduction of toad

Toad is a general term for Anura, an amphibian of Bufonidae and Bufonidae. The most common toad is the big toad, commonly known as toad. The skin is rough, and the back is covered with pimples of all sizes, which are sebaceous glands. The largest pair is the retroauricular gland located above the tympanic membrane of the head. The white venom secreted by these glands is the raw material for making toad venom.

Toads generally refer to more than 300 species of toads belonging to 26 genera. During the day, toads hide in dark places, such as under rocks, in pits or in grass. At night, activities are carried out in ponds, gullies, beaches, fields, vegetable gardens, roadsides or around houses, especially after rain, and they tend to concentrate on dry places to prey on various pests.

Toads mostly lurk in mud or rotten grass at the bottom of the water in winter, and some spend the winter in land soil. It is not only an agricultural guardian who preys on pests, but also integrates medicine, health care and food, so it is known as toad treasure and is a medicinal animal with high economic value.
