1. If you are sure you can attend, you can reply: Thank you for inviting me. I have received the invitation. I will definitely go then. I wish you a happy wedding.

2. If you can't attend, you can reply: I have received an invitation to congratulate you on your happy wedding. Unfortunately, I was too busy that day to congratulate you. I still wish this couple love and happiness for a long time.

3. If you want to express your blessing, you can send messages of blessing, such as: the old moon is tied with red rope, the earth is naturally well matched, the bride is sitting in a sedan chair, a couple, the spring night is warm, the bells and drums sound, the phoenix is happy, the pearl is a hundred years old, and the past life has been asleep. Wish: Happy wedding.
