Also on display are the Crown Pearl goldfish, whose scales resemble pearls inlaid along their bodies, as well as the Lionhead and Ryukin varieties, which are showcased in aquariums along the museum steps. The former impresses with its majestic appearance, while the latter is cherished as a symbol of good fortune, He explains.

As one of the earliest artificially cultivated ornamental fishes in the world, goldfish are deeply rooted in China's history. Beijing stands out as one of the birthplaces of this enduring cultural practice, according to the exhibition organizers.

In Chinese culture, yu, the Chinese word for fish, shares its pronunciation with jade and surplus, bestowing upon goldfish a wealth of symbolism.

They have long been cherished emblems representing abundance and prosperity.

Historical records reflect this deep appreciation: goldfish grace the ponds of imperial palaces and private gardens alike, while also swimming into the hearts and homes of Beijing residents.

Across social spheres, these graceful creatures have endured as living symbols of peace, wealth, good fortune, and happiness, experts agree.

Behind the imperial goldfish's stunning diversity and captivating beauty lie generations of diligent, skilled breeders, whose expertise and dedication have preserved and refined this living art form over centuries.

"Goldfish have long been admired by scholars and poets, and were especially beloved in the imperial court. Historically, the most beautiful goldfish were selected through public competitions and sent to the palace," He says.

As visitors venture deeper into the courtyards, they will discover a row of elegant clay pots arranged under wisteria trees.

"Here we exhibit representative specimens such as the Ranchu goldfish, which is prized for its rounded, egg-shaped body, pronounced head growth, and complete lack of a dorsal fin, together with other rare breeds," He says.

He recommends visitors not to miss the Lemon Gold patterned fish, an exquisite variety characterized by a delicate lemon-yellow hue often adorned with subtle patterns resembling fine brushstrokes or lacework across its scales and fins, as well as the Bubble Eye goldfish that is instantly recognizable for its fluid-filled sacs that develop beneath its upward-pointing eyes, swaying delicately as it moves.

The Cat Lion goldfish, developed through crossbreeding Lionhead and Ranchu goldfish, has also garnered great attention from visitors for its bold, expressive appearance and impressive head growth and elegant dual tail, according to the exhibition organizers.
