This is a vintage or antique Chinese porcelain bowl, likely made in the late Qing Dynasty (1644–1912) or as a Republic period (1912–1949) piece made in the traditional style of earlier wares. Here's a breakdown of the features:
 
Key Characteristics:
Base Mark: The four-character underglaze blue mark on the base reads "Da Qing Qianlong Nian Zhi" (大清乾隆年製), which translates to "Made during the Qianlong reign of the Great Qing." This mark is often apocryphal—used well into the 19th and 20th centuries to honor or imitate earlier imperial wares.
 
Interior Design:
Central Floral Motif in cobalt blue—commonly seen in Qing-style wares.
Red swastika symbols (卍)—a Buddhist symbol of auspiciousness, predating its 20th-century appropriation. Common in Chinese decorative arts for centuries.
Translucent Leaf/Fan Piercing: This is called a "reticulated" or "openwork" porcelain pattern, and this effect is achieved by cutting out shapes from a secondary porcelain layer before firing—quite labor-intensive and often associated with Jingdezhen kilns.
 
Exterior Decoration:
Highly decorative with Imari-style palette (blue underglaze + red and gold overglaze).
Floral sprays and sunburst medallions suggest some Japanese influence, or more likely export appeal.
 
Likely Origin & Date:
Almost certainly Chinese, but made for export or domestic use with some Japanese-style decorative influence.
Likely Republic Period, ca. 1910s–1940s, but could be late Qing. The style was commonly revived in the early 20th century as Chinese porcelain manufacturers catered to both export markets and internal revivalist tastes.
