Most girls are emotional, and the process of pursuing love doesn't care about the result, only about the scenery along the way of love and marriage and the mood of watching the scenery. Therefore, girls feel that marriage must have a marriage proposal ceremony and a marriage ceremony, so that they feel that marriage is complete.
In fact, if conditions permit, it is also good to have a little marriage proposal ceremony, and there is no need to go to extremes. Don't make demands on girls. Cherishing feelings is far more important than ceremony.
