In Chinese social situations, polite words and etiquette are very important. When someone invites you to dinner, you should show respect and gratitude in your words and actions. For example, you could say "Thank you for the invitation, it was a pleasure to have dinner with you***" or "Thank you so much for your hospitality, it made me feel so warm." In addition, when entering the table, you should pay attention to etiquette, such as not using chopsticks first, not talking with food in your mouth, not leaving immediately after eating, etc. These etiquette behaviors can reflect your quality and cultivation, and also make others leave a good impression on you.
