1. Express features with concise words: Dry-picked noodles are a traditional China specialty food. Simple words can be used on billboards to express its unique taste and manufacturing technology, such as "handmade, delicious" and "selected high-quality flour with endless aftertaste".

2. Use pictures to convey information: Using food pictures on billboards can better attract customers' attention, for example, displaying a bowl of dry-picked noodles with good color and fragrance on billboards, or displaying fine craftsmanship in the production process.

3. Use bright colors: Color is one of the most important elements in billboard design, and eye-catching colors can be used to attract customers' attention. For example, you can use bright colors such as yellow, red or orange to make billboards more vivid.
