1. Dear elders and friends, hello, I am the bride's sister. Today is a good day for my sister and brother-in-law to get married. Here, I welcome you on behalf of our family.

My sister is a beautiful woman and my brother-in-law is very handsome. They are a perfect couple. In my impression, my sister has always been a very caring person. For example, she will take good care of me. She cooks for me when my parents are not at home. Sister's cooking is delicious, so you can give your brother-in-law a good meal in the future.

We grew up together, and now she is getting married. As a younger sister, I am reluctant to part with her. I hope my brother-in-law can love you more after marriage, love you more than now, and will not let you be wronged. You should also take care of your brother-in-law and his family. Finally, I wish you a happy wedding and an early birth!

2. Hello, elders and friends. Today is my sister's wedding day. I want to wish my sister and brother-in-law a happy wedding. My sister is two years younger than me. We have a good relationship. We are sisters, more like friends. We will quarrel over a bottle of coke, but we will also share secrets with each other. I will tell my sister what I can't tell my parents.

We are about the same age and have similar preferences. She likes my brother-in-law, and I think my brother-in-law is a good man who loves my sister wholeheartedly. I hope you two can love each other like this forever. If my brother-in-law bullies you one day, I will spare him first. Of course, this is all a joke. You two love each other so much that you will be very happy after marriage.
