What is the relationship between Bo Feng Shui and Senju Hashirama in Naruto?

Namikaze Minato's master is Jiraiya, Jiraiya's master is three generations, the third generation is the second generation apprentice, and the second generation is the younger brother. Do you know what the relationship is? It's a grandmaster! No blood relationship! However, his wife, Wonai, is related to the six generations of immortals. It is not clear what the relationship is now, but there must be a connection, because the vortex clan can seal the seal in six ways, so there seems to be a connection between Chennai and Neibo clan! Naruto is the legacy of Nai's characteristics, but also with maternity! Four generations should be excellent ninjas.
