The same is true of Namikaze Minato, orochimaru and Jiraiya. Therefore, Watergate, Huo Ying's ups and downs of the four generations, will call him a teacher, which is the same as Naruto's habit. Orochimaru didn't teach four generations of Huo Ying anything. At that time, he was still fighting. Maybe even Jiraiya didn't teach Namikaze Minato much. He was busy fighting. What's more, orochimaru usually needs to do research and has no time to do unnecessary things. The mastermind of Watergate was actually Jiraiya, and Jiraiya's good friend was orochimaru. Take Watergate Education in Jiraiya as an example. The relationship between Jiraiya and orochimaru is not bad, so Watergate probably consulted orochimaru, and of course orochimaru is a teacher.
In the fourth generation, it is really called teacher (Sen), which is different from Kakashi (Sang)' s name in ferrets. For whatever reason, there is no difficulty in trying again and again. After all, the fourth generation teacher is Jiraiya, who is a warrior in the same stage as Jiraiya, Gang Shou and orochimaru. They are collectively called Sanren, so orochimaru is equal to Jiraiya in seniority. Four generations of Huo Ying Watergate Incident were Jiraiya's apprentices, and three generations were apprentices. Orochimaru and Jiraiya are brothers. In this connection, orochimaru gave specific guidance when studying at Watergate. Isn't it strange?
In that case, there is nothing wrong with Watergate calling Mr. orochimaru. In addition, it should be said that the translation of subtitle groups is a problem. Now it is said that Libo people obviously worship Sasuke as their teacher, but the conclusion from the subtitle group is that Libo people call Sasuke Uchiha "the old man". Maybe "old gentleman" and "teacher" are the same word in Japanese, so the subtitle group is confused. Watergate originally called orochimaru "the old gentleman", and the subtitle group translated it as "the teacher". Orochimaru used to be a teacher in Nawaki, and she also had red beans. In other words, Python has been a student in forbearance school for a short time. Four generations and Nawaki should belong to the same group, so it's no problem to call Python teacher.
