The core of fast food is still "fast", not the ultimate food value.
Obviously, if people really want to eat the ultimate food, they are willing to spend more money and energy to choose other ways. The core competitiveness is determined as "five minutes, eat a big meal". The "fast" time and the "grand feeling" of the big meal form a strong contrast, which clearly shows the benefits of the product. The picture selects the "one-pot dish" overlooking, which can make consumers have an instant visual pause and buy which pot they want to eat, just like ordering dishes in a restaurant to complete the whole purchase process.
