On the banks of the Puhe River in Xushui Prefecture, Baoding, in the late Qing Dynasty, two melon seed families inherited secret recipes handed down from their ancestors, and each made good melon seeds, which were widely circulated among the people. However, the two families have no contact with each other and operate independently. As time went by, the children of the two families grew up and developed a good impression, and they exchanged family secrets with each other. The two families were particularly shocked when they discovered that the fried melon seeds tasted more delicious than before. After the secret recipe was revealed, they were kicked out of the house. The two wandered to Nanyang, where they opened a melon seed shop and named it Nanyang Melon Seeds. Due to the combination of the two chefs, the melon seeds taste fresh and sweet. Business is booming. But just when their business opened, their trademark had been registered by others. In desperation, they closed their carefully run store.

Many years later, their children returned to the mainland. On the banks of Puhe River in Xushui Prefecture, Baoding, a new melon seed shop was opened, named Yueyang Fresh Melon Seeds. When people tasted it, they immediately thought of the melon seeds from the melon seed family, and the two families reconciled. Today, Yueyang Melon Seeds is the No. 1 brand in Baoding, and it still adheres to ancestral production techniques, windmills and other traditional production methods.
