Internet Valentine's Day is a love festival in the information age, scheduled for May 20th every year. On that day, people boldly express their love through the Internet (Weibo) or mobile phones, and even register for marriage. It can be seen that your friends are very fashionable.
I don't think there is anything special about wedding gifts, as long as they can express your blessings to them. For example, you can send her a bouquet of flowers on the same day to congratulate her on her happy marriage life. In addition to sending flowers, sending a unique cake also means sweetness and is also a good wedding gift. You can also send some blessings to your friends on their marriage, hoping that they will hold hands and grow old together. It is best to be an ornament, so that the newlyweds can keep your gift in a drawer or cabinet or on the table forever, so that they will think of you every time they see it. You can also send some practical things, such as refrigerators, washing machines, bedding, etc., so that your friends don't have to buy them.
