Tei Junsoku (???) (1663–1734), or Cheng Shunze in Chinese, was a Confucian scholar and government official of the Ryukyu Kingdom.
He has been described as being "in an unofficial sense...
the 'minister of education'", and is particularly famous for his contributions to scholarship and education in Okinawa and Japan.
Holding ueekata rank in the Ryukyuan government, he served at times in his career as magistrate of both Nago and Kumemura, and as a member of the Sanshikan, the elite council of three chief advisors to the king.
He is sometimes known as the "Sage of Nago" (????).
It was standard at the time for members of Ryukyu's aristocratic class to have two names.
"Tei Junsoku" was his Chinese-style name, while "Nago Ueekata Chobun" (?? ?? ??), incorporating his domain and rank, was his Yamato or Japanese-style name.
