Domande riguardo a frasi esempio con, spiegazione d'utilizzo di "Arirang"s

A: Arirang is a very old Korean traditional folk song that (many) people have sung since ancient times. (And) The song has (a little bit of) different versions THAT VARY A LITTLE BIT in various regions. But all the Arirang songs have THE same themes (so-called) OF SadNESS, HopelessNESS, AND Love( with hotburn.)
We KoreanS call love sarang. (And) We know what the meaning of sarang is, but MOST Koreans don't know what the meaning of Arirang is, even (including) scholars.
So, I studied MYSELF and found out the real meaning of Arirang. For me, it was AN extraordinary discovery. Now, I can understand the whole Arirang song IN depth.. How lucky (man) I am ! So BECAUSE OF THIS I am going to register my discovery in the patent office AT SOME POINT.
Maybe, I will be the first man TO interpret the most famous Korean traditional folk song , Arirang
