3. Learning the production process: After learning about the products, new employees should receive employee training and learn how to make and serve the products of the tea shop. This includes the standard formula and production process of the tea shop, and new employees need to master the skills of measuring and mixing materials. Employees should also be trained in safety and health regulations to ensure that they operate and clean equipment and tools correctly.

4. Customer service: New employees need to know how to communicate with customers and provide customer service. This includes how to ask questions, how to solve problems, how to deal with customers' special requirements and how to provide suggestions. In addition, new employees can receive sales and promotion skills training to better sell products and services to customers.
