Lv's Pimple Soup is a staple dish of a restaurant chain in Jinan, known for its fresh ingredients and on-site preparation. Lv's Pimple Soup is not a product that is pre-prepared and packaged for sale or take-out delivery. Pre-prepared dishes are dishes that have been washed, cut, matched and processed to completion, and are packaged and preserved in a series of ways, such as frozen or vacuumed, so that consumers only need to consume them after purchase through simple cooking or by opening the package directly, which is characterized by convenience and efficiency. Although the concept of pre-prepared dishes is not yet widely accepted among certain groups of people, many catering and takeaway outlets are actually adopting this format. The fast serving speed of Lui's Pimple Soup is the reason why it is considered as a pre-made dish. One of the waiter's service is also very fast-paced, after checking the menu, they put the timing hourglass on the table, if the sand in the hourglass leaks out of the dish has not been served, this order can be discounted, deepening the customer's suspicion that Lv's Pimple Soup is a pre-cooked dish.
