Wang and Nyima state that after the official title "Education Minister" was granted to Tai Situ Changchub Gyaltsen (1302–1364) by the Yuan court, this title appeared frequently with his name in various Tibetan texts, while his Tibetan title "Degsi" (sic properly sde-srid or desi) is seldom mentioned.
What two people claim the title of Education Minister was often seen next to Tai Situ Changchub Gyaltsen's name in Tibetan texts?
