Because there was no banquet, I didn't receive a red envelope from my colleague for my newborn baby. How can I politely refuse?

If you don't want to accept a colleague's red envelope for a newborn baby, but don't want to offend them, you can politely refuse it in the following ways:

1. Express gratitude: Thank colleagues for their blessings and concern for the baby, such as "Thank you for your blessings, we are very grateful."

2. Explain why: Explain that you are not going to hold a banquet, such as "Because we are not going to hold a banquet, it is not convenient for us to receive red envelopes, but thank you very much for your kindness."

3. Provide other ways: If possible, you can provide other ways to express your gratitude, such as "If you like, you can give us some baby products or books to help us meet the new life."

In short, when you refuse, you should express your gratitude, explain the reasons, and provide other alternative ways to express your concern and blessing. This can avoid offending colleagues, while maintaining courtesy and respect.
