明宣宗
In 1428, the Xuande Emperor granted King Hashi of Chūzan the family name Shang (尚, Shō in Japanese), gave him the title of "Liuqiu Wang" (琉球王, Jap: "Ryūkyū-Ō", King of Ryūkyū), and gifted him a red lacquered tablet with "Chung Shan" (中山, "Chūzan" in Japanese) inscribed in gold, which was then placed on the Chūzonmon gate near Shuri Castle.
