What exactly does "Jin Lan" mean in the word "Yi Jie Jin Lan"?

Yi Jie Jin Lan, this statement comes from Shi Shuo Xin Yu, Gong Shan and Ji, Ruan side, Qi Ruo Jin Lan, and this statement probably comes from Yi Ci Shang, "Two people are together, and the benefits are broken; Words of one heart stink like moss. " What do you mean, that is to say, there is a deep friendship between friends. Later, according to these allusions, friends hit it off, and then they became brothers or sisters of the opposite sex. This is the so-called Jin Lan (seven if Jin Lan).

In the past, it was the custom to exchange spectrum stickers after taking the oath of office, called spectrum or blue spectrum. Therefore, there is another saying called "changing stickers", that is, two people become sworn brothers and tie Jin Lan. According to the custom, when worshipping, write down the "Jin Lan Spectrum" with a pile of red paper, with everyone's name, birthday, hour, place of origin and the names of parents, grandparents and great-grandfathers, then put it on the tablet of heaven and earth, burn incense and worship in turn according to age, and read the oath together. For example, in martial arts novels, it is often seen that "in the name of heaven, today XXX and XXX are half-brothers, not seeking to be born on the same day in the same year, but seeking to die on the same day in the same year" and so on.

Anyone who has read martial arts novels should see the word "Yi Jie Jin Lan". But I'm afraid most people don't know what Jin Lan is or how to marry Jin Lan. Orchids are known as the fragrance of kings. Known as xiangzu. People usually show their personality through orchids, and brotherhood should be as beautiful as orchids, so it makes sense to say "Friendship of Jin Lan", "Friendship of Jin Lan" and "Friendship of Jin Lan".

In the past, when sworn brothers, they had to exchange genealogies as evidence, which was called "Jin Lan's genealogy" or "Lan's genealogy". It is so called because "two people are United, and their profits are broken", and their words are the same, and their thoughts and feelings are the same, so their "one-hearted words stink like blue" and smell like blue.
