Life at Ocean Park Hong Kong

First Months

Jia Jia spent her first months in Ocean Park’s behind-the-scenes nursing area, receiving round-the-clock care from the park’s veterinary and keeper team. Her mother Ying Ying demonstrated attentive maternal behavior, allowing the care team to conduct regular health checks.

100-Day Celebration (November 23, 2024)

Ocean Park held a traditional Chinese 100-day celebration for the twins — a significant milestone in Chinese culture. The event attracted widespread media attention across Hong Kong and mainland China.

Public Debut (February 2025)

On February 15, 2025 — their half-birthday — Ocean Park held a naming competition launch ceremony. The twins made their first public appearance the following day on February 16, drawing large crowds eager to see Hong Kong’s first home-grown pandas.

Naming Competition

From February 15 to March 7, 2025, Ocean Park invited Hong Kong residents to submit name suggestions. The competition received over 35,700 entries, reflecting the public’s deep affection for the twin cubs. On May 27, 2025, the park announced the official names: “Jia Jia” (加加) for the female and “De De” (得得) for the male.

Expanded Habitat (May 2025)

On May 27, 2025, Jia Jia, her brother De De, and mother Ying Ying moved to an expanded habitat in the “Giant Panda Adventure” exhibition area at Ocean Park. The new space features climbing structures, enrichment items, and a highland area designed to stimulate the cubs’ physical and cognitive development.

Personality & Character

Curious Explorer

Park keepers describe Jia Jia as a naturally curious and independent cub. She enjoys:

• Climbing trees and wooden structures in her habitat
• Exploring every corner of her enclosure
• Spending time alone investigating enrichment items

Growing Independence

As she matured, Jia Jia began spending more time away from her mother, exploring independently while staying within visual range. This behavior aligns with normal developmental patterns for giant panda cubs.

Learning to Eat Bamboo

By May 2025, at approximately 9 months old, Jia Jia was observed mimicking her mother’s bamboo-eating behavior — picking up bamboo stalks and attempting to bite them, though not yet consuming them successfully. This represents a normal developmental milestone as cubs transition from milk to a bamboo-based diet.
