Silver bars have a profound and far-reaching historical background, which began in the summer, flourished in the Tang Dynasty, flourished in the Ming and Qing Dynasties, and became famous today. It is said that when Yi Yin, the prime minister of Shang Dynasty, assisted Shang Tang, Yi Yin, who was born in the kitchen, found a straw in Miaocun, south of Di Ku Temple, ate it raw and tasted it, and actually cooked it into a peerless delicacy. In order to help Shang Tang beat Xia Jie, Yi Yin killed the chef. Then, he won the favor of Sister Xi, Xia Jie's favorite woman, and made Xia Jie eat silver bars through Sister Xi. Sister Xi made up "If you want to live forever, white wine and silver swallows" to coax Xia Jie into drinking. Xia Jie "can't bear to put down chopsticks, the more he drinks, the more fragrant he becomes." Since then, his drinking capacity has soared, and he has neglected state affairs. On the fifth day of the first month of this year, Shang Tang and Yi Yin cooperated with each other and finally overthrew the rule of Xia Dynasty.

It seems mysterious to occupy a country with a small dish. But through this novel-sized legend, we can see the delicious and refreshing taste of silver bars. If you don't believe me, look at this joke about food again: "A thousand banquets are better than people, and you dare to boast with silver bars. It is the first mouth to press the table. " The Grand Banquet Picture shows that Shang Tang destroyed Xia Hou in Bo (now Yanshi), and called thousands of ancient and rare old people to hold a state banquet to discuss the strategy of governing the country. The old people at the banquet were full of praise after tasting the silver bars, which led to the above words.

In the process of helping Shang Tang destroy Xia Hou, Yi Yin taught you the planting method and cooking method of silver bars in order to make people get more benefits. People appreciated Yi Yin's kindness, so they named this plant "Silver Bar". Later, people around Xibo ancient city planted this dish in exchange for glistening silver, so it was also called "silver bar".

Since Yi Yin cooked a root vegetable into a delicious dish in the world, the silver bar dish itself has become superior, and its value has doubled, so it has become the favorite of emperors in past dynasties. "Yanshi County Records" records: "Silver bars are the tribute of the imperial courts in past dynasties, and the silver bars in Sizhuang area are the best". During the Kaiyuan period of the Tang Dynasty, Xuanzang, a monk who came back from India to learn Buddhist scriptures (the prototype of Tang Priest in Journey to the West), presented silver bars from his hometown of Yanshi Michael Chen as a tribute to Li Shimin, Emperor Taizong. After Li Shimin tasted it, he was very happy. "Your brother and delicacies are wonders of the world, and Yanshi is really outstanding!" Therefore, "water chestnut" became another name for silver bars, and Emperor Taizong also gave the dishes made of "Yanshi silver bars" as "dietary treasures". Later, the Empress of the Tang Dynasty and the Emperor Qianlong of the Qing Dynasty climbed the Goushan Mountain in the southeast of Yanshi to taste the silver bars, leaving behind poems praising the silver bars. After the founding of People's Republic of China (PRC), Premier Zhou Enlai and President Liu Shaoqi visited Dongsizhuang Village in yanshi city successively. Premier Zhou praised the silver bars happily after tasting them: "The silver bars are really delicious." President Liu Shaoqi even humorously praised: "In addition to gold bars, there are silver bars in the world!"

In the 1980s, with the development of reform and opening up and commodity economy, Yanshi people began to try to make silver bars into cans and sell them at home and abroad, so that people all over the world can taste the delicious silver bars at any time. Products such as canned silver bars are exported to Thailand, Vietnam, Mongolia, Russia and other 8 countries and regions, which are well received by merchants.

In 200 1 year, the heads of state attending the APEC meeting in Shanghai tasted Yanshi silver bar and called it "the miracle of the world". In 2006, the "Yiyuanchun Hotel" in yanshi city cooked Yanshi silver bar with shrimp, which was fresh and delicious, and had health care function besides fatigue. It won the championship in the "Man-Han Banquet" held by CCTV, and Yanshi Silver Bar was rated as the "golden dish" in China cooking.
