随Sui与and隋Sui朝Dynasty
Character 随originally was used for the Sui Dynasty (581—618) because the surname of the First Emperor in the Sui Dynasty was 随. However, later the emperor changed the character from 随to隋for his Dynasty, because 随has the radical 辶which implies motion. The emperor considered motion a sign of turbulence and instability, something he did not want for his country.
