For example, what does Chiyo mean? For example, what does Chiyo mean?
Analysis:
Yes, that's Tokugawa Ieyasu.
Takechiyo was the name before Fu Yuan. After Fu Yuan, it was called Songping Yuankang.
Later, with the rise of status, after the unification of Sanhe and Jun, Matsuhei Yuankang tampered with the Tokugawa family tree and wrote Matsuhei's family as a branch of Tokugawa family related to Genji. So as to achieve the purpose of improving social status.
This was very common in Japan at that time. For example, the name of the monkey was Toyotomi, the original name of Shangshan Qixin was Long Tail Jinghu (Shangshan was the special surname of Guanling in Guandong), and Kitajima Zaoyun (a branch of Imagawa).
Anyway, the Japanese are so * * * that even their surnames can be changed.
