If you mean the groom is kneeling, that's another matter.

In modern weddings, there is a part where the groom kneels on one knee and holds flowers in his hand. Kneeling or not depends mainly on the groom's own wishes. The MC needs to communicate well with the newcomers in advance. If the groom feels it necessary to show his gentlemanly side, he can be advised to kneel on one knee. If the groom feels embarrassed and doesn't want to kneel on one knee, then this link can be cancelled.

Another thing to note is: 1 In the process of the wedding ceremony, if the groom kneels, he kneels on one knee, not on both knees. When the bride is pregnant, she can't kneel.

The above is aimed at modern weddings. If it's a Chinese, Chinese or other wedding, that's another matter.
