What should I say when I become sworn?

When choosing an auspicious day (the environment should be quiet), it is extremely disrespectful to wear slippers, trousers and undershirts. It is best to get a haircut and prepare a fresh, healthy and young rooster. Everyone has a big bowl (big bowl shows heroism) facing Guan Gong, raising his arm and twisting the cock struggling to drop blood into the bowl (the bowl is not full of water, just half full). At the same time, I knelt down to kowtow to Guan Yu (without Guan Yu facing south), raised my bowl at the same time, and stretched out my arms together, saying, I became brothers with so-and-so at such-and-so time and place (loud and powerful voice and serious expression). From now on, so-and-so and I are willing to live and die together, * * * suffering, * * * wealth, the world can see! If you have a second thought, God radar pi!

Special requirements:

Ancient science and technology were underdeveloped, and there were no audio and video recordings. Even if you are sworn brothers, you should keep pace with the times. Who cares if the evidence is in hand?
