 In the "Records of the Grand Historian", the population of Linzi in the fourth and third centuries BC was said to be 70,000 households, with at least 210,000 adult males.Scholars today believe this was somewhat exaggerated.The kings of Qi and the Qi state acted as patrons of the Jixia Academy (ca 315-285 BC) in Linzi, the earliest and largest (in its time) center of learning in China.
