In ancient times, dragons and phoenixes not only symbolized auspiciousness and gods, but also symbolized kingship and nobility. Ordinary people or princes who have twins will not be called dragons and phoenixes directly, because such titles are only enjoyed by royalty or nobility.

In the royal family, dragons and phoenixes are often used to symbolize the emperor and queen or royal blood. If a royal or aristocratic baby gives birth to twins, it will usually be named with auspicious words, such as "Dragon Zhang Fengzi".

In ancient China, many nobles and literati regarded the dragon and phoenix as auspicious signs, and believed that the appearance of the dragon and phoenix heralded auspiciousness and good things were approaching. Therefore, ordinary people or princes and ministers may feel lucky and happy if they have twins, but they will not directly name their children Longfeng.

In short, in ancient China, dragons and phoenixes had a special status and symbolic significance, and ordinary people or princes and ministers could not call their children by such names.
