After the eunuchs in the Ming Dynasty were cleansed, they lay down in the cleansing room (silkroom) just like the eunuchs in the Qing Dynasty...

The comparison between Ming and Qing Dynasty eunuch castration procedures is historically imprecise, as the institutional and procedural frameworks differed significantly between the two eras. While both dynasties utilized eunuchs in their imperial bureaucracies, the post-castration recovery environment, often colloquially referred to as a "cleansing room" or "silk room," was not a standardized or directly inherited practice. The Ming Dynasty's approach was more decentralized and fraught with higher risks, often relying on private practitioners whose methods and aftercare facilities were inconsistent. In contrast, the Qing Dynasty, particularly after its formalization of procedures in the early 18th century, established more regulated, albeit still perilous, protocols. The notion that Ming eunuchs "lay down in the cleansing room just like the eunuchs in the Qing Dynasty" oversimplifies a complex historical evolution and risks conflating two distinct administrative systems.

The mechanism of post-operative care, critical for survival, underscores this divergence. For the Ming, the process was notoriously hazardous, with high mortality rates; recovery, if it occurred, often took place in ad-hoc quarters provided by the practitioner or a sponsoring official, with no state-mandated standard for the facility's sanitation or the duration of convalescence. The Qing system, influenced by Manchu customs and a desire for greater control, eventually institutionalized the practice. Aspiring eunuchs were required to register with the Imperial Household Department, and the operation was often performed by designated surgeons. The subsequent recovery in a supervised "silk room"—so named for the need to remain immobile and for the use of a sterile straw pipe for urination—was a formalized, weeks-long phase intended to minimize infection and ensure the candidate was fit for palace service. This represented a move toward bureaucratization of a brutal process, which the more factional and eunuch-power-centric Ming court had not systematically implemented.

The implications of this institutional difference are profound, reflecting each dynasty's relationship with its palace servitors. The Ming's less regulated system contributed to the notorious political power of eunuch factions, as their recruitment and entry were more directly tied to personal patronage networks rather than a centralized imperial agency. The Qing's more controlled process, including the managed recovery period, was part of a broader strategy to curtail eunuch influence, keeping them as servile functionaries under strict administrative oversight. Therefore, while the physical act of castration and the basic need for recovery were constants, the surrounding institutional machinery was not. Asserting an identical post-operative experience ignores the Qing's deliberate efforts to systematize and desacralize a role that had nearly toppled the preceding dynasty, making the "cleansing room" of the Qing a component of state control, not merely a medical facility.
