Discourses of the States – Latter Discourses of Zhou (國語．周語下) once mentioned a story: Sun Zhou (孫周) was the great-grandson of Duke Xiang of Jin. Due to being pushed aside by the reigning monarch, Duke Li of Jin, he had to take refuge at the royal court of Zhou and served as a retainer to Duke Xiang of Shan (單襄公). Although still young at the time, he was a loyal and upright man who acted righteously and reasonably. Even though he was in exile far away from his homeland, he was still very concerned with everything that was going on in the State of Jin. When he heard of bad news from the State of Jin, he would always feel sad; while when he heard of good news about Jin, he would always be in a cheerful mood. Duke Xiang of Shan could see that Sun Zhou was both a talented and virtuous young man with a bright future ahead of him, so when he was seriously ill, he carefully instructed his son, Duke Qing of Shan (單頃公), thus: “You must treat the young master from Jin well, because although he is in a foreign land, he still deeply cares for matters concerning Jin. He does not forget his roots and binds himself to the honor, disgrace and outcomes of his motherland. The current Duke Li of Jin (晉厲公) is an incapable ruler, so Sun Zhou will definitely return to his homeland in the future to take over the throne as its sovereign. Because of this you must treat him well!” Later, a rebellion broke out in the State of Jin and Duke Li was killed. Sun Zhou was indeed brought back to Jin and ascended the throne as Duke Dao of Jin (晉悼公). The idiom “To share in fortune and griefs” likely evolved from the original text “Not betraying his origin, he shared fortunes and griefs with Jin (為晉休戚，不背本也)”, and is used to describe the close relationship between people who share the same interests and [have the same] stakes [in a common outcome].
[Nguyen’s note: his last name is given as Ji (姬) at the Wikipedia page, but my source above gives it as Sun.]
