1, the myths and legends of Ina Nanhai and Long Fu are mainly taken from the fairy tales recorded in ancient books, such as the ghost novel "The Romance of Gods" in Ming Dynasty, The Journey to the West in Yuan and Ming Dynasties and "Three Religions Seeking Gods". Nezha, the hero, is loved by people for his naive courage and fearless spirit. In the story, because the demon dragon killed people and made waves, Nezha made a scene in the Dragon Palace Water House. Because this story is a household name, it has been adapted many times and created a number of animated film and television works. Among them, the hand-drawn animated film Where is the Sea, created by Shanghai Animation Film Studio in the late 1970s, is the first large-scale color wide-screen animated feature film in China. Together with opera-style music, mythical music works, known as "colorful, elegant and imaginative", have been widely praised at home and abroad and are still regarded as classic old films. At the same time, it is also one of the primary school texts in the 1990s, and it also appears in some children's books.

It is an ancient myth and legend well-known among China people, and it is also a classic plot recorded in ancient literary works such as Searching for Gods by Three Religions, Romance of Gods, and The Journey to the West.

The myth and legend of "What made the sea" is widely circulated in China, and appears in many ancient literary novels and drama images. Shanghai Fine Arts Film Company also incorporated this mythical theme into its production, taking the classic old film What Is the Sea Made from 65438-0979 as its representative work, which belongs to intangible cultural heritage.
