You can say from your own point of view: "I am very lucky to marry my mother-in-law today." I will do my duty and be a good wife in the future. "
I can praise my in-laws: "My husband often tells me how my in-laws are at home, and I will be filial to them."
You can say from your partner's point of view, "I am very lucky to get married in this family." I will definitely take over the responsibility of my mother-in-law and take care of my other half. At the same time, I will do my best to honor the two. "
You can look at your relatives and friends like this: "My parents-in-law married my daughter-in-law today, and I believe I can live comfortably and happily in the future, just like today's occasion!"
The above is for reference only, and some old people may not understand it.
But you just need to remember that it is not difficult to reveal what you said in this toast as long as you have the respect to chat with your elders at ordinary times.
Because if your in-laws agree to your marriage, they must be very satisfied with you. No matter what you say, even if you say a lot of meaningless compliments, they will still smile and nod.
And if your in-laws don't welcome you at all, then there is no need to hold this wedding, right?
In China, the most difficult relationship is the relationship between mother-in-law and daughter-in-law. I hope the topic owner must be careful not to wronged himself.
Finally, congratulations on your happy wedding and all the best!
