On the surface, Qingzhou does not belong to Zhao Yao, but in reality, it has long since become Zhao Yao's territory.
Besides doing business and building merchant and warships in Qingzhou, Zhao Yao also established an intelligence agency there.
The intelligence agency in Qingzhou predates the one in Swamp Prefecture. At that time, maritime bans were not yet lifted, but Qingzhou was the only place that allowed foreign ships to dock, the only place where foreign merchants could do business in Great Zhou. It was essential to establish an intelligence agency to inquire about the news and intentions of these foreign merchants.
Zhao Yao had high hopes for Qingzhou and made preparations early on. He had a comprehensive understanding of matters concerning Qingzhou.
Prince Chu recalled that Zhao Yao had mentioned to him that his uncle did business in Qingzhou and was quite familiar with its affairs.
