Miaomiao, the true daughter of the Zhenhai Marquis Manor who ended up wandering among the common folk, was abandoned on the reef during a typhoon by her greedy adoptive parents when she was only four years old. At her moment of life or death, she was desperately saved by the Yan family, poor fishermen. Having survived by a miracle, Miaomiao awakened the 'golden finger' of being able to understand the language of marine creatures, henceforth transforming into a little lucky star. Not only did she make the destitute Yan family's fish and shrimp burst their bamboo baskets and bring in a fortune daily, but under the divine assists of marine giants such as dolphins and giant whales, she repeatedly shattered the conspiracies of vicious relatives and powerful court officials in the capital. In the end, Miaomiao's true identity came to light, perfectly fusing blood kinship with the grace of upbringing, leading the Yan family and the Marquis Manor toward the pinnacle of prosperity, and composing a legend that blessed all common people.
