Brand story of Shandong Tianshi E-Commerce Co., Ltd.: Late one night in the early 1980s, several outsiders came to Liuzhou hungry and found that a Rice noodles stall was about to close. However, there is no necessary bone soup for Rice noodles, only a pot of snail soup is left. Granny Wang, the stall owner, was very worried. She put Rice noodles in snail soup and cooked them with vegetables, peanuts and other side dishes. Finally, they made some special Rice noodles, which were eaten by outsiders and shouted delicious. Grandma Wang kept this in mind and gradually improved its ingredients and production in the later stage, gradually forming the prototype of screw powder. When everyone smelled the aroma of the screw powder cooked by their mother-in-law, they all rushed to buy screw powder from her, and she simply sold the screw powder. By the mid-1980s, screw powder reached its first peak and established its position as the top snack in Liuzhou.
