In the orange groves, a huge orange tree grows, big enough to shelter all the orange groves. Among the neatly arranged wild orange trees, oranges are hanging on the branches. This thousand-year-old orange tree, after thousands of years of practice, has become a little orange fairy with excellent internal strength. The little orange fairy transformed into a human form and came to the world. She met Wang Datan, a man who built mountains and bridges, and started a dreamy, romantic and funny bond between her and Wang Datan.
