description This abstract describes a bilingual Qing dynasty customs document comprising two distinct administrative notices issued by the Yuehai Customs House in Guangdong Province. The first is a vessel departure permit dated to the thirty-first year of the Qianlong reign (1766), authorising the Western ship under the command of foreign merchant João de Gama (transliterated as Ruòwàng Jiā Dǎ Rě’ān) to sail from Yuehai to Luzon, having paid all requisite duties; it records crew size (49), provisions (22 *dàn* 5 *shēng* rice), armament (6 muskets, 12 small cannons), and the presence of one enslaved boy (*mài zǐ*) classified as taxable human cargo. The second notice, dated to the second lunar month of the thirty-first year of the Guangxu reign (1905), is an official proclamation signed by Supervisor Chen Zi, reiterating strict compliance with customs duty regulations for all imported and exported goods under imperial mandate. Both texts bear multiple red and black seals—including *Yuèhǎi Guān*, *Qīng*, and *Ji Ri*—and marginalia referencing authority from the Ministry of Internal Affairs. The document serves as primary evidence of Qing maritime administration, cross-border trade regulation, colonial-era commercial practices, and the institutional recording of coerced labour within official customs frameworks.
