英文摘要：

Bijing（毕竟） is a mood adverb emphasizing cause or the radical characteris- tics of the entities. However, it is a muhifunctional expression in classical Chinese. The following problems concerning Bijing are controversial among the researchers of Chinese： （1） When did the word Bijing appear in history？ （2） When did the temporal adverb Bijing appear and how to paraphrase it？ （3） How did Bijing as an evaluative mood adverb evolve？ （4） How did Bijing as an interrogative mood adverb evolve？ Based on the close exploration of the largescale linguistic data, this paper attempts to solve the above-mentioned problems in terms of lexicalization and grammaticalization theory from a historical perspective.
