The pheasant is also known as frog, water fowl, sitting fish, including common frogs, bullfrogs. Because of its tender meat is better than chicken meat, so it is called field chicken.

The frog is a cold-blooded animal, and the body temperature of cold-blooded animals is affected by the air temperature, and as the air temperature gets colder, their body temperature will gradually drop. When the temperature drops to a certain level, some animals will be frozen to death, in order to survive, cold-blooded animals like frogs into the soil, in a state of pseudo-death, as a way to avoid the cold, wait until the next spring when the ground temperature rises and then come out of the activity, which is the hibernation of the fowls.
