Longan is a special product in southern China, which is rich in nutrition. The pulp contains vitamin C, vitamin K, crude protein, inorganic salts and other essential nutrients. Dried longan with fresh longan fruit has the effects of nourishing the heart, benefiting the brand, nourishing blood and calming the nerves, and can be used to treat weakness after illness, anemia, flaccidity and postpartum blood deficiency. However, people suffering from exogenous pathogens and full phlegm should not eat longan meat, and pregnant women should also avoid taking it, which is easy to cause miscarriage.

Legend has it that a long time ago, a gentleman named Qian led the local people to build dams and dikes, cultivate fields and raise fish. A few years later, the flooded land became a land of fish and rice, and people lived and worked in peace.

However, money officials are still childless after three years of marriage, and they often feel sad about it. The local people were deeply moved by Qian Yuanwei's diligence and love for the people, and expressed their willingness to marry their daughters to Qian Yuanwei as concubines. Finally, Mr. Qian got a son at the age of 53. Money outside the family is happy, and it is impossible to get together day and night.

Unfortunately, due to congenital deficiency and acquired pampering, Mr. Qian's son is thin and small, and often has a fever and cough. At the age of ten, he still looks like a child of four or five. To this end, Mr. Qian asked for medical advice for him, and invited famous doctors to taste folk remedies, but he just couldn't be strong. Mrs. Far Prince heard the news and rushed to Qianfu all the way. She kindly said to Mr. Qian, "Longan can cure fatigue and weakness. Your son wants to exercise, and I think he must eat longan. "

Mr. Qian asked inexplicably, "Madam, why?" Lady Wang said, "Nezha killed the third prince of the East China Sea Dragon King and dug longan. At this time, there happened to be a poor child named Haizi, who was weak due to lack of nutrition and often fell ill. After months of nursing, he still hasn't improved. Nezha immediately gave the longan to Haizi after hearing the news. After eating longan, Haizi not only became strong and no longer sick, but also gradually grew into a big man. After marriage, she gave birth to thirteen dragons and phoenixes and lived for more than 130 years.
