Jiegua, also known as Maogua, is named after "one melon per section". Other varieties of zucchini mostly grow on vines, and black-haired zucchini grows in the melon shed beside the fish pond. Zucchini absorbs enough sunlight and water reflected from the water surface, and has a bright Wuqin body, also known as "Shui Ying Melon".

Zucchini is rich in plant fiber, which can promote gastrointestinal peristalsis, protect human gastrointestinal tract, help improve gastrointestinal function, and thus effectively relieve constipation.
