Actually, the things Bao Qin knows don't completely overlap with Wan Dongliu's side. After all, the Four Symbols Sect doesn't hold meetings with Tang Wanju all the time; everyone does their own thing, and many matters rely solely on mutual understanding.
Just like how the Four Symbols Sect used Tang Buqi's birthday banquet as a setup, and Tang Buqi himself was unaware of it. Huangfu Qing and San Niang thought that if they had informed him earlier, he might have spilled the beans.
Even though Marquis Wu has cultivated Jiangnan into prosperity over thirty years, everyone still doesn't trust Tang Buqi's intelligence... This thirty-year prosperity mainly relies on the boom of maritime trade; even a pig could fly in such conditions. Besides, Tang Wanju occasionally intervenes and guides personally, which is why Bao Qin is seemingly here to inspect.
