国庆请家人聚餐怎么说英语

To invite your family to a meal for National Day in English, you could say:
"Hey family, let's get together for a National Day meal to celebrate. Who's in?"
"National Day is coming up, and I was thinking it would be nice to gather as a family for a meal. What do you think?"
"I was hoping we could all come together for a National Day meal. Who's available to join me?"
"National Day is a great opportunity to spend time with family and celebrate. Would anyone be interested in joining me for a meal to mark the occasion?"
I hope these suggestions are helpful! Let me know if you have any other questions.
