The number of people sent by the bride cannot include the staff of the wedding company, the bride's parents, and the bride herself. Generally, there are 5-15 people, depending on the number of people received by the groom. The number of people the man accepts as a bride is odd, and the number of people the woman sends as a bride is also odd, which perfectly forms an even number, symbolizing a pair.
For example, if the man accepts the bride with 5 people, then the woman may send the bride with 5 or 7 people, which can create an even number of 10 or 12. This is the expression of "returning the single to the double", symbolizing the beauty and happiness of the couple.
Most of the people who send the bride off are unmarried, but not all of them. They also need a few close and authoritative elders to help them "suppress the situation", such as uncles and aunts. In addition, the bridesmaid group is also indispensable.
In some places, it is customary for parents not to send their daughters off, mainly because they are afraid that parents will be too reluctant to part with their daughters, causing excessive sadness and affecting the festive atmosphere of the wedding.
