My boyfriend wants to take you to meet your parents during the Spring Festival. How can I politely refuse?

You can tell him that the Spring Festival is a time for family reunion, and you two are not married, so legally and morally, neither of you is a real family. If you haven't met your parents yet, you can tell him that before going to each other's house for the New Year, both parents should have met and asked their parents' opinions. Otherwise, it's really inappropriate to go to a new year's party before my parents have met.
