Zhou Shu was second to two famous scholars, Dong Fu (董扶) and Ren An (任安), in terms of fame.
[3] Sometime between 194 and 214, when Liu Zhang was the Governor of Yi Province (covering present-day Sichuan and Chongqing), he recruited Zhou Qun to serve in his administration as an Assistant Officer for Education (師友從事).
In 220, Zhou Qun's prediction came true as the Cao Wei state replaced the Eastern Han dynasty.
[6] In January 213, after seeing another astronomical phenomenon, Zhou Qun predicted that the warlords in western China would lose their territories.
[7] In 214, after the warlord Liu Bei took control of Yi Province, he appointed Zhou Qun as acting Colonel of the Scholars (儒林校尉) in his administration.
At the time, Zhang Yu, another diviner serving under Liu Bei, also said, "If you attack Hanzhong, your army will suffer a defeat."
During the campaign, Liu Bei also ordered Wu Lan (吳蘭) and Lei Tong (雷銅) to lead a detachment of troops from his main army to attack Wudu Commandery (武都郡; around present-day Longnan, Gansu), but, as Zhou Qun warned him, this detachment ended up being completely destroyed by Cao Cao's forces.
[8] Liu Bei later nominated Zhou Qun as a maocai (茂才; a cultivated talent recommended for a government post).
One day, while he was gathering herbs in the Min Mountains, he encountered a white ape who climbed down from a steep cliff and stood right in front of him.
In the Spring and Autumn period, people like Ziwei (子韋), Ziye (子野) and Bizao (禆竈) managed to think of more accurate means of calculating time, but they never truly grasped the essence of astronomy.
