2. Visit liquor production areas: If your area is one of the main production areas of liquor, you can visit local wineries, wine culture streets, etc. to learn about local products and suppliers. During such a visit, you can also communicate directly with suppliers and discuss cooperation matters.

3. Ask people in the industry: You can ask your peers in the catering industry or retail industry about the suppliers of the liquor they purchase. These people usually have rich experience and cooperation resources and can provide valuable supplier information.

4. Participate in industry exhibitions: Participate in exhibitions and exhibitions in the liquor industry, which usually have many suppliers participating. You can learn more about products and cooperation information through face-to-face communication and negotiation with suppliers.

5. Use social media: Search for relevant liquor supplier accounts on social media platforms such as WeChat and Weibo, follow their dynamics, and contact them to negotiate cooperation. No matter which approach you take, you need to conduct sufficient investigation and screening to confirm the supplier's reputation and product quality to ensure the reliability and quality of cooperation.
