When friends get married, it is generally more appropriate to give gifts on the wedding day or in advance. The time of giving gifts can be determined according to personal circumstances and customs. On the wedding day, you can choose to bring gifts to the wedding site to express your blessings and support to your friends. If you can't attend the wedding in person, you can send gifts in advance to ensure that the gifts are delivered before the wedding. The specific gift-giving method can be chosen according to your own preferences and financial strength, which can be cash, gifts or other practical items.
