Tell a story about chicken feathers for sugar? I have only heard the idiom trivial.

The Political Economy of Chicken Feathers for Sugar When I was a child, I always saw two bamboo baskets around the busy Spring Festival in the twelfth lunar month. On the lid of the bamboo basket, there are two small boxes filled with small sweets. The small peddler drum in my hand is jingling. I shouted with a foreign accent, "Chicken feathers for sugar, chicken feathers for sugar!" " The drumming of the peddler brought laughter and sweetness to the children. "How many sweets can I exchange for this packet of chicken feathers?" A child took a bag of chicken feathers to the vendor's owner and asked. "Three sweets!" "I only give three sugars and two more for this big bag of chicken feathers!" The child kept begging. "Ok, here are five!" The child reached out his hand and ran home with five little sweets in his arms. Running and shouting: "Mom, I have five sweets!" " ""two for my brother, two for you and one for later, do you hear? "Mom was telling me. Little brother rushed over. " Dude, where's the sugar? ""What's the hurry? Two for mom, two for you and one for me! "Being a brother really seems like wanting to be a brother. While giving my brother two, I ran to my mother with three sweets and said, "mom, mom, try this candy!" """You kids are so greedy, you two eat!" Mother likes touching her eldest son's head very much. "Mom, if you don't eat, I won't eat!" "Good boy, that mother has a taste!" The mother took the smallest candy from her eldest son and put it in her mouth, saying, "This candy is so sweet!" " "A pack of chicken feathers brought five sweets, which added a lot of sweetness and affection to the mother and son and their brothers and sisters. These businessmen who came to our ancient Huizhou to do a small business of exchanging chicken feathers for sugar are all from Yiwu, Zhejiang. They carry the burden of vendors on their shoulders, sleep in the wind, starve and do small businesses that others will never want to do. We asked them what chicken feathers are used for, and their answer was that some chicken feathers are tied into feather dusters, fine down and duck down are mixed to make down jackets, and some are used as fertilizers. Anyway, all kinds of chicken feathers are useful. You can imagine how hard it is for Yiwu people to do this kind of business, and their position in people's minds can be imagined. I roared through the city on a spacious express train. When people described this place as Yiwu, I felt happy memories of exchanging chicken feathers for sugar when I was a child. Sigh the fighting spirit of Yiwu people and their ability to exchange chicken feathers for sugar. The spring breeze of reform and opening up has spread all over China. In the spirit of exchanging chicken feathers for sugar, Yiwu people took the lead in starting a small business, spontaneously formed a primary market and accumulated funds. Under the guidance and support of correct policies, they gradually changed from shed shops and street markets to shopping malls. With the continuous development of the market and the continuous accumulation of funds, a large modern and information-based trade city has been established. When merchants introduced themselves, they used Jinhua Yiwu at first, and then unconsciously transformed it into Yiwu, Zhejiang. I don't know when they quietly opened their hearts to the world with Yiwu Commodity City in China, and the United Nations also came to Yiwu Trade City to purchase small commodities. Langsha socks industry was originally a small socks factory run by Weng Rongdi brothers. After a decade or two of hard work, a Langsha socks industry group was born and developed. Today, Langsha socks industry has become the largest socks industry enterprise in the world. Langsha, as the first brand of aircraft carrier in China socks industry, has been exported to more than 100 countries and regions. The formation of a pair of socks industrial chain reflects the great changes in Yiwu market from one side. The Yiwu Commodity Index, the only weather vane of China, is also produced here. The traffic in Yiwu is also very fast and convenient. Express trains no longer whizzed past, and three expressways, namely Hangjinqu, Jinliwen and Jinyong, also passed through Yiwu and the airport, extending in all directions. The local population of Yiwu is only 697,000, but the temporary population is approaching the million mark, and there are still 200,000 floating population every day. Businessmen from all over the world also come to Yiwu for gold. On the streets of Yiwu, shop names written in Chinese, English, Arabic and Korean can be seen everywhere.
