The famous product "Late Goods of Haixi". Jihongtan (Jinhongtan) is rich in seafood, and the most precious and famous is the late goods of Haixi. "Final cargo" refers to a tiny shrimp floating on the water surface where the estuary enters the sea. The word "final goods" has not been universally used in the whole country so far, and it can't be found in all kinds of dictionaries, but there is a record of "final goods" in Laoshan County Records. It is a special product in the northern part of Jiaozhou Bay, and it is named as "the end of marine products" because it is too small. After careful cooking, the final product tastes delicious and is a delicacy on the table. Known as "the goods at the end of Haixi, the smaller the more expensive". According to legend, in the Qing Dynasty, the sea tyrants occupied the sea area, and the fishermen in Haixi who made a living by fishing at sea lost their vitality. The fishermen who are desperate want to dredge the government and punish the sea tyrants through the monks stationed in the capital of the village. Several smart and strong fishermen secretly went to Haikou to catch the last goods, put them into porcelain jars at home, and camped out in Beijing for days to find the monk. The monk gave a banquet to the court officials the next day. After the banquet, the final goods were served. After eating, the officials were full of praise and asked what it was. The monk told the name of the dish and sighed in tears, telling the story. At the early morning of the next day, officials told the emperor that they wanted to eradicate the sea tyrants and restore justice to the people in Haixi. The emperor granted permission, so he issued an imperial edict to eradicate the sea tyrants, so that fishermen in Haixi could freely fish and produce. "Hanwa Seawater Tofu". Seawater tofu in Jihongtan (Jinhongtan) has a unique flavor. As early as the end of the Qing Dynasty and the beginning of the Republic of China, people in Toucun, Henan Province used the clear and sweet Hongjiang river water and local soybeans as raw materials to produce tofu with seawater, which was delicate, tender, smooth and delicious, and was deeply loved by people. Therefore, there are more than 3 households and more than 2 employees in the village, specializing in tofu business in Qingdao. Later, the Hanwa people across the river also mastered this craft. In 193s, Hanwa people also went to Qingdao to do tofu business, with 28 households and 27 employees. In the early 195s,

most of the production backbones of bean products factories in Qingdao were from Hanwa and Henan.

Since ancient times, it has enjoyed "the benefits of fishing and salt" by taking advantage of its geographical location. Salt production in the territory was first published in Yugong. Since the Ming Dynasty, salt people have drenched brine, set up pots to support stoves, fried with firewood, cooked salt by the sea, and capital sprouted, and salt industry is the most famous. In the 29th year of Guangxu in Qing Dynasty (193), Wan Yongfang, a villager from Nanwan, led his people to open a salt field, replacing frying with drying, and opening Jiaozhou Bay salt industry to frying as a precedent for drying. The salt produced is not only sold at home, but also exported to North Korea, Japan, Russia and other countries. After the founding of New China, the government increased investment, reformed the old beach and adopted advanced technology, which promoted the development of salt industry in the region.

Its leading product "Haiyu Brand" was rated as a provincial and ministerial quality product with large grain, white color and high purity.
