Hello, this item is a Chinese porcelain floor vase decorated in famille rose style enamels, likely produced during the late 20th century, approximately 1970s to 1990s. The dense floral scrolling decoration, pastel palette, molded rim band, and interior painted motifs are characteristic of export decorative porcelain rather than imperial or early Republican period production. The red four character mark on the base appears to be an apocryphal reign mark, a common practice in modern Chinese ceramics where historical style marks are applied decoratively rather than indicating true period manufacture.

From a market standpoint, large decorative Chinese porcelain vases of this type, measuring around 40 cm in height, typically sell in the secondary market between 150 USD and 350 USD depending on condition, decorative quality, and demand.
