The term "Biyun" (碧雲) had already been set in print as "Azure Clouds" by 1931, at least in the venerable "Mathews Chinese English Dictionary" from Harvard Press. There also was a mark of "Made for the Hall of Azure Clouds" in use by the Kangxi Period (1662-1722), as well as another of "Made for the Hall of Green Jade" in use at that same time. The character Bi/碧 actually can be used to denote either blue or green jade).
The late German connoisseur of Chinese and Japanese porcelain, Georg Weishaupt, had in his extensive collection a small square brushpot with landscapes on all sides and an iron red mark on the base of "Made for the Terrace of Azure Clouds" (Bi yun xuan Zhi - 碧雲軒製) within a single square border. The item was pictured in the last Weishaupt catalog, published in 2002 under the title, "The Great Fortune". Its date estimate was given as "19th /20th century".
Your set of porcelain for the scholar's desk appears to be of better than average artistic quality, with what looks to be scenes in the life of a scholar within "faux bois" borders. However, the photos don't really lend themselves to a close-up appreciation of brushwork and other points of technique that might reveal clues regarding who did or inspired the painting. The mark itself is somewhat atypical in its more heavily written characters and double border, when compared to the other examples found online (see links below), the majority of which, in my opinion, look good enough to be of the Republic period. A couple that seem questionable should be self-evident.
