Secondly, there is no date limit for taking the oath, only whether "like-minded" are the same. Like-minded, no matter how good life is. Like-minded people are good friends and brothers even if they don't become sworn friends. It is suggested to get together in off-year and take an oath in front of Guan Lao.
Third, I want to remind all young people who are interested in taking an oath, but the purpose of taking an oath should be pure, to benefit the public and do good things for society, so that people can remember your benefits and let history record your achievements.
