What is an alliance brother?

Pledge/oath is a standard etiquette procedure, that is, on a voluntary basis, through consultation and agreement, 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 hum three sacrifices, namely pork, fish, eggs (one for each person) and a live chicken (the male is a rooster and the female is a female), "Jin Lan Spectrum". After the ceremony, everyone will bring a wick and "Jin Lan Music". Then, kill the chicken, drop the chicken blood into the red wine, pierce the middle finger of everyone's left hand (the woman's right hand) with the 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 are also called "blood alliance".

No matter men, women and children, there is no limit to the number of oaths/oaths, but it must be an odd number. In the same year, the same sex became sworn, with men called brothers and women called sisters. It is usually carried out in adolescence, and most of them are like-minded, or in the same boat, or have their own needs. Sacrificial etiquette and custom: the clan does not become sworn; It is the in-laws who do not become sworn; Those who have a generation gap do not become sworn; Those who do not agree with the eight characters do not become sworn; Those who break clan rules do not become sworn (if they made enemies with other clans before, they vowed not to get married with a certain clan, get married, etc.). With the progress of society and the improvement of civilization, people think that as long as they get along well, they don't have to stick to a certain form.

After the swearing-in ceremony in ancient times, people who took part in the swearing-in ceremony were called brothers. Some of them added the words "Qi", "Lan" and "Friendship" before their names, and some of them were commonly called eldest brother, second child and third child? It means life and death and * * *, sharing weal and woe. In case of wedding, funeral and celebration, etc. They all associate like brothers.
