- Japanese/Chinese: 程 泰祚 (Tei Taiso / Chéng Tàizuò)
Tei Taiso, or Chéng Tàizuò, was a Ryukyuan scholar-aristocrat who traveled to China at least twice as a member of official embassies. He is perhaps best known as the father of reformer Tei Junsoku.
Tei Teiso traveled to China in 1663 as a member of a group escorting the first Qing Dynasty investiture mission home to China. He then stayed there for two years.
Teiso returned to China in the early 1670s as a member of a regular tribute mission, but died in Suzhou in 1675.
