See Through All the Scenery

Baoyue Brothel was already a net that extended all over the world. Although various factions knew the world's largest brothel was the property of the Fan family, they had no way to control it. After all, it was a legitimate business. No countries had laws that could control it. Baoyue Brothel had good conditions. They were polite and kind to the women that worked for them, truly enjoyed by the customers, and had harmony between their labor and management. With Fan Xian's power as a support and Xia Mingji and Zhaoshang money house for financial assistance, in four short years, it had extended its reach to every place.

Although Baoyue Brothel's intelligence gathering was nowhere near as professional or powerful as the Overwatch Council's, it provided Fan Xian another source of information.
