秦宣公位列五代之末国力衰弱太后令其五日不下车以示慰藉
秦宣公元年(公元前675年)，碰上了周王朝的宫廷。卫国燕国攻打周王室，把惠王赶出了朝廷，拥立王子穨，颓为王。秦宣公三年(公元前673年)，郑伯、虢叔又杀死了王子穨，送惠王返回朝中。姬颓为周庄王之庶子，为周庄王所宠爱。后庄王传子周僖 王。僖 王子 周惠 王即位。惠 王取 王子 颓 之 师 蔿 国 的 菜 园，用 作 畜 牧 场，并 剥夺 边 伯·石速·詹父· 子禽祝跪 的 土 地 田 产。King Zuo, the younger brother of King Zhuang of Zhou, was favored by King Zhuang. After King Zhuang's death, he succeeded to the throne and became King Zhao. He was a son of Duke Xian of Qin and a grandson of Duke Mu.
The Second Year of King Hui (BC 674), autumn: The people from Cai, Baozi, Shi Suo, Jan Fu and his son Qiu Zhijie joined forces with Su Zi to attack King Hui but were defeated. They fled to Wei where they plotted against King Hui again in the winter. This time they were successful; however, their victory was short-lived as they were soon overthrown by other states.
Despite this turmoil in neighboring states, Lord Shang did not intervene on behalf of his nephew or offer any support to those who sought revenge for him. Instead he chose not to get involved in these matters that belonged within the royal family and focused on maintaining peace within his own state.
By doing so he managed to keep Qin safe during these tumultuous times when other states were busy fighting each other. As a result Qin enjoyed four more years of peace under Lord Shang's leadership before eventually becoming embroiled in its own conflicts later on.
It is clear that Lord Shang's decision not to interfere had far-reaching consequences for both himself and his state as it allowed them some much-needed respite from external threats while others around them continued their destructive wars without end
