Regarding the founder of the Qin dynasty, who was his grandfather?
King Xiaowen of Qin King Xiaowen of Qin (reigned 250 BC) was a Chinese king, who had a very brief reign. He is also known as Lord Anguo (安國君). His grandson was Emperor Qin Shi Huang.
Emperor Jing of Han Emperor Jing of Han (188–141 BC), personal name Liu Qi (劉啟), was the sixth emperor of the Chinese Han dynasty from 157 to 141 BC. His reign saw the limiting of the power of the feudal kings/princes which resulted in the Rebellion of the Seven States in 154 BC. Emperor Jing managed to crush the revolt and princes were thereafter denied rights to appoint ministers for their fiefs. This move consolidated central power which paved the way for the long reign of his son Emperor Wu of Han.
