In addition to managing relations with China, Đinh Bộ Lĩnh energetically reformed the administration and the armed forces of Vietnam in order to strengthen the foundations of the new state. He established a royal court and a hierarchy of civil and military servants. Đinh Bộ Lĩnh also instituted a rigorous justice system in which treason was punishable by being cooked in a vat of boiling oil or by being fed to a caged tiger, so as to provide a deterrent to all who threatened the new order in the kingdom.
