Mingguang mung beans have been exported since 1920, with annual sales of about 10 million jins. In 1976, a new variety was tested and its quality exceeded the export standard, and it was known as the super bright green. In 1981, he won the fourth prize for provincial scientific and technological achievements, and in 1983, he was named "Minglu No. 1" by the province. The "Minglvye" wine brewed from Minglvye is praised by the Beijing Evening News (Beijing Evening News) as the "wonderful flower in wine".

Mingguang mung bean is a famous specialty product of Mingguang City, Anhui Province, which is well-known both at home and abroad. It is referred to as Mingmung bean and enjoys a high reputation in domestic and foreign markets. The local working people have the tradition and experience of growing mung beans since ancient times. Guandian, located about 15 kilometers south of Mingguang City, was originally a small village with about 20 families living there, most of whom came from other places to settle here. It is said that one of them, whose surname is Guan, has a large family. In addition to cultivating wasteland and farming, there is still a surplus of labor force. The head of the household with this surname is not only good at farming, but also has a flexible mind and is good at thinking. At that time, he discovered that the village he lived in was a must-pass for transportation from north to south. Passers-by often asked residents for a place to rest and a bowl of tea to quench their thirst. Some even asked for food and accommodation. He realized that if he opened a restaurant, wouldn't he be able to make money? ! According to the theory, this is actually a business opportunity. It is said that during the Guangxu period of the Qing Dynasty, about 130 years ago, a man named Guan built two houses at the intersection of the village and opened a small restaurant for passers-by to eat, sleep and rest. The small hotel was called the Guanjia Hotel. As time went by, it became simply called Guan Dian. Some people also say that a person named Guan opened a shop at the entrance of the village, which is called a small shop opened by a person named Guan, or Guandian for short. In short, at that time, as long as people mentioned Guan shop, they could understand its meaning. Later, with the increase in the immigrant population, by the end of the Qing Dynasty, a market town was formed here, and Guandian was also inherited as the place name. And the 147th day of the lunar calendar was designated as the market day. In 1912, the Qing government built the Tianjin-Pukou Railway and set up a station here named Guandian.

After the Tianjin-Puzhou Railway was opened to traffic, brothers Lin Weipu (also known as Lin Huanyao) and Lin Weijin (also known as Lin Shuyao) from Liuhe, Jiangsu Province, followed their father (whose name is unknown) to Laishuikou to Guandian to do grain business. , there is also a shareholder named Zhang Shengsan (nicknamed Zhang Er Zhuozi), who is mainly responsible for inspecting the quality of grain. Because their business in Shuikou was not going well, they gave the grain store an auspicious business name - Sheng Changxiang, hoping that the business would prosper and prosper. It was this Shengchangxiang that made a historic contribution to the future fame of Mingguang mung beans at home and abroad.

Not long after Sheng Changxiang opened, Mr. Lin passed away, and the Lin brothers were in charge. Later, in order to expand their business, they set up an office in Nanjing. The Lin brothers lived in Nanjing and Zhang Shengsan became the manager. Lin Weipu died of illness in 1932. After Japan surrendered in 1945, Lin Weijin and Zhang Shengsan died successively. After they passed away one after another, Shengchangxiang Grain Store began to decline, and changed from independent operation to acquisition by agents. This situation lasted until the dissolution of the Grain Store at the end of 1948.

Around 1940, it was the heyday of Guandian’s grain business. At that time, there were more than 70 large and small grain stores (one said 72, another said 75). In addition to Shengchangxiang Grain Store, large and small grain stores Other grain shops include Shen Kangxiang (from Tianjin), Lang Dasheng (from Zhejiang), Tongyixing, Yuda, Xingfa, etc. The bosses of these grain stores mainly come from Tianjin, Zhejiang, and Liuhe, and are called the Tianjin Gang, Zhejiang Gang, and Liuhe Gang. Large grain houses do business directly with merchants, while small grain houses organize the supply of goods for big banks and earn handling fees and processing fees. More than 5,000 tons of miscellaneous grains are shipped from Guandian to relevant ports every year. When did Mingguang mung beans become famous? Who created the brand? This is an issue that has not been mentioned in many materials in the past. The investigation results show that Shengchang Xiang Grain Company used its past sales channels to export to Southeast Asian countries and Hong Kong and Macao through resellers around 1915; Zhang Shengsan (nicknamed Zhang Er Zhuozi) is the creditor of Minglu Chuangpai.

In the early days, Sheng Changxiang dealt in mung beans, sesame seeds, peanuts, soybeans and other miscellaneous grains. Mung beans not only accounted for a large proportion, but were also particularly favored by merchants. Zhang Shengsan, who has always been business-minded, decided to build a mung bean production base for himself after taking charge of Shengchang Xiang Grain Store. It was this business philosophy that laid a solid foundation for the reputation of Mingguang Mung Bean at home and abroad.

According to all the elderly people interviewed, Zhang Shengsan bought a carload of high-quality mung beans from Shandong (one said 30 tons, another said 50 tons), and after selecting them, he gave them to Erdao dealers on credit (essentially providing seeds). They let the beans to the surrounding farmers to plant, and then they collect the beans harvested by the farmers and hand them over to the grain bank.

At that time, people said that he was a fool, and perhaps the nickname Zhang Er was born from this time. It was precisely because of Zhang Er Zhuozi's courage that not only did Sheng Changxiang's business grow bigger and bigger, but Zhang Er Zhuozi's reputation also became famous far and wide.

At that time, the grain store in charge of the store did not have a specialized domestic and foreign sales organization, and mainly resold through merchants in Shanghai, Guangzhou, Wuxi and other places. The mung beans and miscellaneous grains shipped by Fanshengchangxiang Grain Store are all carefully selected and processed before being sent to dealers. After several years of hard work by Zhang Shengsan, the integrity of Shengchang Xiangliang Co., Ltd. and its resellers became increasingly high. Later, whenever the goods shipped by Shengchang Xiangliang Co., Ltd., resellers from all over the country saw the signature on the sacks as Shengchang Xiangliang Co., Ltd. Changxiang (before 1932, it was Guandian Changxiang of Xuyi County, Anhui Province) mark, all are exempt from inspection. This was truly remarkable at the time.

Shengchang Xiang Grain Store was a relatively large grain store in Guandian at that time, with three courtyards and several large grain villages. During the acquisition season, there was a lot of excitement, and more than 20 day laborers were hired at that time. Zhang Shengsan not only has a branch in Shimenshan, but also sends people to Wuhe, Xuyi and other places to organize supply of goods. It is said that the bank transfers more than 40 wagons and more than 1,000 tons of mung beans every year, accounting for more than one-fifth of the total sales of the store.

There were many varieties of mung beans at that time, such as big locust leaves, big tuan leaves, small tuan leaves, big mosaic leaves, small mosaic leaves, string ground dragons, etc. Shengchang Xiang Grain Company swapped them to produce bright green processing. They are particular about and strictly classified. Except for the hand-picked Class A beans, the rest must go through three to four screenings before being packaged. At that time, mung beans were divided into three categories. The good ones were type A, called Tecai (hand-picked beans); type B, called Daming Green (large seeds); type C, called Chongcai; and type D, called Xiaoming Green. Class AB is supplied for export, and class CD is mainly sold to the domestic market. Due to the level of quality, there is a huge disparity in acquisitions and export sales between grades. However, it is this quality price difference that promotes farmers to plant high-quality bright greens.

The mung beans sent by the bank to various resellers are usually 90 kilograms per sack, and some are also 100 kilograms. Their beans have uniform grains, and their quality ratios of moisture, impurities, imperfect grains, and different-colored grains are all lower than the export regulations. In the 1970s, Mingguang Distillery used Minglu as raw material to brew a "Minglu liquid" that is rich in aroma, mellow and mellow, clear and clear, has an elegant bean aroma, has a long aftertaste, and has the functions of detoxifying, keeping out the cold, and relaxing muscles. , as soon as it came out in 1980, it was unanimously praised by wine critics, calling it "a wonder among wines"; "People's Daily", "Economic Reference", "Beijing Evening News" and other newspapers have published praise articles; "Minglu" "Liquor" is also regarded as a "treasure among wines" by consumers. Its brewing process obtained the invention patent certificate from the State Intellectual Property Office in October 2003.

For more than 20 years from the 1980s to 2005, Minglu used to supply Zhongnanhai as a "tribute" (special needs product). Each time, the Provincial Party Committee General Office issues a supply task. The seed company, with the cooperation of the public security department, selects and packs the seeds into small packages, and then the Provincial Public Security Department sends a special vehicle to transport them away. The annual supply ranges from about 400 to 1,000 kilograms. Due to the influence of production, domestic and foreign markets were gradually occupied by other provinces, and even Minglu was first registered by others. In response to the problems existing in Minglu production, representatives of the Municipal People's Congress and members of the Chinese People's Political Consultative Conference have put forward suggestions on the development of mung bean production for several consecutive years. Municipal Party Committee Secretary Zhang Songjian emphasized: "We cannot let Minglu be lost in our hands." Mayor Zhu Qinglong held a special executive meeting to discuss how to revitalize the Minglu industry, build a good Minglu base, develop new Minglu varieties, and improve Minglu output and quality. We have carefully studied other issues, and allocated 100,000 yuan from agricultural science and technology fees for trademark registration, commodity barcoding, and declaration of green food. In the municipal tourism plan, Minglu is designated as a green tourism product to supply tourists. In 2004, our city established the Mingguang Mung Bean Association. In the same year, it applied to the Trademark Office of the State Administration for Industry and Commerce for origin protection and registration of "Mingguang Mung Bean" and is currently waiting for the acceptance result.

Minglu is the main specialty and traditional export material of Mingguang. It enjoys a high reputation in domestic and foreign markets. We hope that through the careful implementation of the plan, Mingguang mung bean production and sales will achieve greater success.
