The description of sitting without standing tall seems to describe the difference in height between standing and sitting for a certain zodiac animal. In the zodiac, each animal has its own unique body posture and habits. To find out which zodiac signs fit this description, we can look at the characteristics of each zodiac sign individually.
First, let's look at rats. Rodents are usually smaller in size, whether sitting or standing, and the difference in height is not significant. Therefore, this description is less applicable to rats.
Then there are the cows. Oxen appear tall and mighty when standing and lower when sitting. This difference in height between standing and sitting is consistent with the description of "sitting without standing tall". However, considering that other zodiac signs may also have similar characteristics, we cannot immediately determine that the ox is the correct answer.
And then there are the tigers. The tiger is majestic when standing and more docile when sitting. However, the difference in the size of tigers when standing and sitting is not significant, so this description does not apply well to tigers.
Next up is the rabbit. Rabbits are usually smaller in size and do not vary much in height whether standing or sitting. Therefore, this description does not apply to rabbits as well.
Let's look at the dragon. Dragons are mythical creatures with no actual height to measure. Therefore, we cannot be sure if this description applies to dragons.
And then there are the snakes. There is indeed a noticeable difference in the height of snakes when standing (i.e., holding their heads up) and sitting (i.e., curled up). When the snake curls up, its height is much lower than when its head is raised. This seems to be more consistent with the description of "sitting without standing high".
Next up are the horses. Horses appear tall and straight when standing and low when sitting. This difference in height between standing and sitting is consistent with the description of "sitting without standing tall". However, considering that the previously mentioned ox and snake may also fit this description, we still need to move on to other zodiac signs.
And then there are the sheep. The difference in height between standing and sitting sheep is not significant, so this description is less applicable to sheep.
Next up are the monkeys. Monkeys are active and active, but the difference in height is not noticeable whether standing or sitting. Therefore, this description does not apply to monkeys as well.
Finally, chickens. Chickens appear taller when standing and lower when sitting. However, this difference in height is not as significant as that of cows, horses, and snakes, so this description may not be very accurate.
Considering the characteristics of each of the above zodiac signs, we can find that the height difference between the snake and the horse when standing and sitting is the most significant. When the snake curls up, its height is much lower than when its head is raised. Horses, on the other hand, appear lower when they sit down, and are not as tall and straight as they are when they stand. Therefore, both zodiac signs can be considered candidates for the description of "sitting without standing tall".
However, if we consider the context and moral of this description further, we may be more inclined to choose the snake as the answer. Because in some cultures, snakes are often used to symbolize sinister, cunning, or scheming qualities. The description of "sitting without standing tall" may be an allusion to some people or things that seem to be low-key on the surface, but are actually scheming. Therefore, from this point of view, the snake seems to be more in line with the connotation of this description.
To sum up, although the horse is also one of the zodiac signs that fits the description of "sitting without standing tall", considering factors such as context and meaning, we are more inclined to choose the snake as the answer. Of course, this is only a possible process of interpretation and reasoning, and different cultures and contexts may have different interpretations and understandings.
