I always wondered how some people are so knowledgeable about jianghu affairs when there is no reliable way to transfer that information. Someone like Zhang Sanfeng doesn't seem nosy enough to send spies and students out just to scout for information, and he barely leaves his meditation chamber nevermind Wudang mountain, yet he has vast knowledge of wulin.
Zhang Cuisan had no idea Yin Tianzheng was the leader of Heavenly Eagle Sect, yet Zhang Sanfeng is able to comment on YTZ's character. Zhang Cuisan is supposed to be the one wondering jianghu and learning the latest news, how does ZSF know, especially when the Heavenly Eagle Sect is a new sect.
Feel free to answer my question or join in on noting things that don't make much sense!
