The process of brothers becoming sworn brothers.

There is a standardized etiquette procedure for the conclusion of the ceremony, that is, on a voluntary basis, through consultation and agreement, we choose an auspicious day, hang Guan Gong and other gods in a place that everyone thinks is more suitable, such as the ancestral temple, and hem three sacrifices, namely pork, fish and eggs (one for each person according to the number of people), and a live chicken (the male is the rooster and the female is the female). One copy of "Jin Lan Spectrum" is given to each person, and each person's name is written in the order of age, and their fingerprints are pressed. After the ceremony, each person will take a wick of incense and "Jin Lan Music". Then, kill the chicken, drop the chicken blood into the red wine, pierce the middle finger of each person's left hand (the woman's right hand) with a needle tip, drop the blood into the red wine, stir it evenly, sprinkle three drops on the ground first, and finally take a sip in order of age, and put the rest in front of the statue of Guan Gong. This form, some also called "blood alliance".

The number of people who make vows is unlimited, but it must be an odd number. In the same year, people of the same sex become sworn, men are called brothers, and women are called sisters. Generally, it is carried out in adolescence, and most of them are like-minded, or they are in the same boat or have their own needs. In the old society, there were many rituals and customs of becoming sworn: those who were relatives did not become sworn; It is the in-laws who do not become sworn; Those with generational differences do not become sworn; Those who do not agree with the eight characters do not become sworn; Those who break the clan rules don't become sworn (in the past, if they made enmity with other clans, they vowed to make rules not to marry or marry a certain clan); Those who fail to pass the oath ceremony are not officially sworn, and so on. With the progress of society and the improvement of civilization, people think that as long as they get along well with each other, they don't have to stick to a certain form. Of course, in reality, there are still some young people who are sworn, and they are relatively indifferent to the old etiquette. The ceremony is generally simple, and most of them are oral vows. The grand ones hold vows in front of Guan Gong statues, "ancestral temples" or other gods according to etiquette and customs. Young people who want to become allies generally have to get the consent of all parents before they become sworn, because their elders are more experienced and cautious.

after the swearing-in ceremony, the people who take part in the swearing-in ceremony are called brothers, some of them add the words "Qi", "Lan" and "Friendship" before the salutation, and some of them are commonly called eldest brother, second child and third child ... which means life and death and * * *, sharing weal and woe. In case of weddings, funerals, festivals, etc., they all associate as brothers.
