Due to the long-term limitation of the breeding area and the quality of the breeders, the naming of goldfish in China is ambiguous. China Aquatic Ornamental Fish Research Association issued the "China Goldfish Directory", which subdivided the goldfish with head tumor in eggs as follows, hoping to get the correction from the insiders. Usually, the egg-shaped tiger head type and the egg-shaped lion head type are collectively called tiger head goldfish. However, lion-headed eggs are different from tiger-headed eggs. The strawberry sarcoma on the head is not only bulging and plump, but also wraps the cheeks downwards, and the eyes are half trapped in the sarcoma. Head sarcoma is obviously better than tiger head type. The longevity called in Fuzhou and the cat and lion called in Wuhan can all be attributed to the egg lion head type. Although the head tumor of egg-shaped tiger head type is not as good as that of lion head type, it is compact and energetic, which can reflect the momentum of tiger head. Description of classification characteristics: the head tumor of goose, a representative variety of eggs, is concentrated on the top of the head, which is square or mushroom-shaped, but its cheeks are not raised and distributed on both cheeks. The head is square and does not spread to both sides. Lion's head tumor, a king-shaped egg, is extremely rich and comparable to chrysanthemums. Sarcoma on both sides of the oral cavity is full, expanding the oval domain of cats and lions. The head tumor does not protrude, and the sarcoma on both sides of the oral cavity protrudes forward from the Japanese red and blue domain.
