How to distinguish the male and female of Gu Long?

It is said that dragons have both sexes. The horn waves of the male dragon are concave and steep, the eyes are deep, the nose is open, the horns are sharp, the scales are dense, the upper part is strong and the lower part is strong, and the fire is bright red. The female dragon horn often droops, the waves are flat, the eyes are wide, the nose is straight, the neck is round, the scales are thin, and the tail is stronger than the abdomen. There are four sources of dragons: viviparous, oviparous, moist and metaplasia. When a dragon is viviparous or oviparous, it often cannot be a dragon or a species. One is called like to scream, and it is not old. The ancients often carved its shape on the clock knob. One likes music and is called prison cow. People sometimes carve it on the piano. One likes water, called kiss. People carved its shape on the bridge. One kind likes adventure, called mocking wind, and people carve its shape on the corner of the temple; There is also a favorite character called exorcism (tourmaline font has no characters, so it is substituted), and people carve its shape on stone tablets. There is also a man who likes to carry heavy loads, named Ba Xia, whose shape is carved on the pedestal in the temple. There is also an armadillo that likes to argue, and people carve its shape on the prison door; There is also a kind of sister-in-law, who likes to sit, and people sit on the statues carved in the temple; There is also a kind of artistry, which likes to kill people. People carve its shape on the handle. So there is a saying: there are nine kinds of dragons, each with its own differences. The dragon in ancient legend is a magical and changeable animal. In later generations, the dragon became the exclusive name of feudal emperors, which was probably unexpected!
