The deer is a graceful and charming animal, widely loved for its unique form and gentle temperament. They usually have long legs and a slender body, with smooth hair that varies in color with the season and species. Most deer are brighter in the spring and summer, and dimmer in the fall and winter to provide better cover in the woods.

Deer live in groups, and there is a strong social bond, especially between mother and calf. Adult males usually mate with females during the estrus season and are often left alone at other times. During this time, the males will engage in fierce gladiatorial fights for the right to mate, showing their strength and courage.

The deer's diet consists mainly of plants, especially young leaves, bark and grass. During the season when food is abundant, deer move frequently in search of the most abundant feeding spots. This process not only maintains their survival, but also invisibly promotes the growth of plants and ecological balance.

Despite their docile appearance, deer also possess no small amount of survival wisdom. When sensing danger, deer can escape at a very high speed, and the height and flexibility of the jump make it have a strong ability to protect itself in the face of danger. At the same time, deer has a very keen sense of smell and hearing, can detect changes in the surrounding environment in time.

In human culture, deer often symbolize innocence, peace and harmony with nature. They appear in many fairy tales and works of art, representing the softness and beauty of life. In some areas, deer are also important economic animals, driving local ecotourism and becoming an object of appreciation and protection.

However, the deer's environment is often under threat. Urban expansion, environmental pollution and habitat destruction have affected the survival of deer.
