What is sworn brother oath?

1. Make brotherly love, trust each other in life and death, help each other in good and ill, help each other in adversity, let outsiders disturb you, let brothers disturb you, and heaven and earth testify that mountains and rivers are allies. If you violate this oath, you will be destroyed by the devil!

2. There is a sky above, and there is thick soil below as evidence. Mountains and rivers are allies, and the four seas are similar. Today, I married Jin Lan, sharing weal and woe. I don't want to be born on the same day in the same year, but I want to die on the same day in the same year. If you violate this matter, the devil take the hindmost.

There are standardized etiquette procedures for summing up the meaning.

That is, on a voluntary basis, after consensus, choose an auspicious day, in a place that everyone thinks is more suitable, such as the ancestral temple, hang the gods of Guan Gong and others, hum and hum three sacrifices, namely pork, fish and eggs (one for each person), a live chicken (male rooster, female), a bowl of red wine and Jin Lan Spectrum.

Everyone sends out a copy of Jin Lan Spectrum, writes down everyone's name in chronological order, and presses their fingerprints. 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".
