Writing ideas: First of all, thank all the guests for coming and expressing their enthusiasm, then congratulate the newcomers and look forward to the future.

Example:

Ladies and gentlemen,

Good evening everyone. Today, we gather together to hold a warm engagement ceremony for my son xx and Miss xx. Thank you for coming to congratulate me in your busy schedule. Here, we express our warm welcome and heartfelt thanks! Soon, you will step into the wedding hall. I hope you can work together in the future to create a better future for each other.

As a father, I have three words to say to this couple. First, I hope you can understand each other and share the same experience in future fires. Second, I hope you respect your parents and be filial to them. Being married means that your parents are old. Remember to go home often. Third, I hope you will continue to work hard, continue to create, and repay the country and society with practical actions. Finally, I wish you a happy life, mutual respect and love.
