70-Year-Olds Are Doing Business Around the World with Vests

Once time traveled to the 1970s, Tangyuan was nicknamed a "silly girl" for no reason. She finally learned the local dialect and wanted to change everyone's minds. Suddenly she discovered that the bundled game could actually change her face and dress up, and she could also open a vest account all over the world! Who cares what others call her? Of course making money is important! The random vest actually arrived in Xiangjiang: Do you need a sweater? Thirty-one pieces (knitted for one dollar each) Do you need tea? Eight yuan per catty (charged at two cents per catty) Do you need a hair tie? Eight cents each (sewn for two cents each) Random vests have arrived in country M again: A hair tie... Do you want it? One piece each (still two cents a piece to sew) Rice...15 Cents a pound? Give me 20,000 pounds! (It sells for 20 cents per catty in the mainland!) Flour...8 Cents a pound? Give me one hundred thousand catties! (It's still sold in the Mainland for 20 cents per catty!) Intention: Self-reliance and continuous self-improvement.
