Running a Leisurely Fishing Business in the 1960S

[Next book: I Transmigrated to the Eighties and Happily Became a Father. Please add it to your collection.] Jiang Xiaoling has a secret that nobody knows but her. When she turned seventeen, a System called Xianyu suddenly appeared in her mind. The System is fascinating. It has all kinds of strange things she's never seen before, and best of all, she can trade items with other people! Through it, Xiaoling trades nothing but junk for all sorts of food! Poster: The auction record for the "A Sea of Red Across the Nation" stamp has been broken again! On the eighteenth of this month, a block of four in excellent condition sold for 1.688 million yuan! Jiang Xiaoling's gaze fell on the letter she'd just torn open. She froze! There, at the edge of the envelope, was a stamp exactly like the one on the poster, and she was tearing it in half! Xiaoling picked up a cigarette box her neighbor had thrown away and sold it for 180 yuan. That was enough to trade for fifty jin of rice and thirty jin of white flour. She stole an old newspaper she'd picked up to patch the roof and sold it for 239 yuan. Just like that, she had all the supplies she needed for New Year. - Shao Yang was fed up with his father's nagging. With no other choice, he opened an Xianyu account to help sell the homemade sausages and cured meat from their home. To his surprise, the first customer asked him, "Can I trade stamps for your sausages? The one mentioned on the poster, 'A Sea of Red Across the Nation.' Just one sausage is fine." Shao Yang stared at the message for a long time, then slowly typed: "?" Are you kidding me?! But when he received the package the young lady had sent in exchange, he went wild! The young lady likes sausages? Take them, take them, take them all! The cured meat is delicious too. I'll send some to her as well! And my dad makes the best smoked chicken and duck. Miss, I'll send it all to you! As long as you remember my name: Shao Yang. When you get more good stuff, remember to trade it to me next time~ One day, Shao Yang was looking through the family photo album when his father pointed to an old photograph and said, "This is your grandma. It's a shame she suffered so much when she was young and passed away before you were born. She never got to enjoy a single day of her life." The more Shao Yang looked, the stranger it seemed. He finally couldn't help asking, "What's Grandma's name...?" "Jiang Xiaoling. Ling, as in water chestnut." Shao Yang: !!! And so, this is a story about sending food across time to Grandma and her family. Warnings: 1) The heroine was reborn from the eighties. She has never seen modern things and doesn't have a mindset that transcends her era, so please don't expect too much of her. She's just an ordinary person. 2) This story is set in a fictional world with lots of invented details, so please don't compare it to real life. Theme: Self-reliance brings endless joy.
