The complement-marking auxiliary words Dao and Qi in Xinshao dialect in Hunan can connect the predicate to the state complement or degree complement. As to the frequency of use, Dao is the highest while Qi is the lowest. Both of them were deprived from the grammaticalization of result complements. Through comparison, it is found that when the complement is just a qualitative adjective or a monosyllable adjective, then it must be connected by another complement-marking auxiliary word De to the predicate.
