一句一句分析。
第一大句：It is said that in the seventh century BC during the Spring and Autumn Period,Jie Zitui was a good official inthe Jin State,working for Prince Chong’er.

对这一大从句进行分析：in the seventh century BC during the Spring and Autumn Period是介词短语做时间状语，从句中的Jie Zitui was a good official inthe Jin State 是从句的主干，working for Prince Chong’er.是动名词做伴随状语，对主干中的Jie Zitui进行补充说明。
