《盟水斋存牍》是明末一部史料价值颇高的文集。作者颜俊彦,崇祯元年至四年任广州推官,《盟水斋存牍》就是他在任时处理的勘合、谳略、翻案、矜审、公移等的结集,涉及刑事、民事、诉讼等司法及行政实务,对明末广州、澳门贸易及相关管理制度变动也多有记载。如海道副使原来督察海防,兼管夷务、带管市舶,万历年间明神宗派太监李凤、高寀督办粤、闽榷税,使海道副使的超常权力被剥离,退出市舶管理。明中叶主管朝贡贸易的清闲衙门市舶司重新掌管税收,还协助海禁、防范接济走私等,权势膨胀,产生严重的贪污腐化,号称“濒海贪泉”。此外,广州、澳门的“揽头”、“铺行”、“夷商纲纪”也十分活跃,参与贸易。这些对了解明末“广中事例”演变具有重要的史料价值。 “Mengshui vegetarian” is a collection of high historical documents in the late Ming Dynasty. The author Yan Junyan and Chongzhen were promoted to officials in Guangzhou in the first year to the fourth year. The “League of Merits and Disputes” is a collection of reconnaissance, omission, reversal, trial and public transference of criminal cases, civil cases and lawsuits And other judicial and administrative practices, the late Ming Canton and Macao trade and related changes in management systems are also recorded. For example, Hokkaido made the original Inspector Haiphong co-defend the country affairs and took control of the market. In the Wanli years, the Ming Shenzong Eunuch eunuch Li Feng scrupulously supervised the administration of Guangdong and Fujian taxation and expelled the extraordinary power of Haido envoy to withdraw from the municipal administration. In the middle of Ming Dynasty, the Qing Dynasty Yamen Shipping Department, which is in charge of the tributary trade, re-administers the tax revenue, assists the sea ban and smuggles the economy, swells its power and causes serious corruption and corruption. In addition, Guangzhou, Macao’s “head”, “shop”, “Yishi Gangji” is also very active and involved in trade. These are of great historical value for understanding the evolution of “Guangzhong Case” in the late Ming Dynasty.
