李勣
Almost immediately after taking the throne, Emperor Gaozong promoted Li Shiji to be the general in charge of Luoyang. (As Emperor Gaozong also, at the same time, declared naming taboo was to be observed as to the characters "shi" and "min" (Emperor Taizong, as his name had two common characters, previously only ordered that naming taboo was to be observed against the use of "shimin" consecutively), thereafter, Li Shiji became known as Li Ji.) Almost as immediately, Emperor Gaozong repromoted him back to the post of chancellor "de facto". He then further made him "Puye" (Executive State Secretary).
