The 10th Anniversary Gift

March–April 2007: The Hong Kong Home Affairs Bureau held a naming competition for pandas 606 and 610, receiving about 13,000 entries from residents. The results were announced at the airport on April 26, 2007, the very day the pair arrived. The jury included Louis Cha (金庸), who proposed the names “Ying Ying” (盈盈) and “Le Le” (乐乐) — the names ultimately selected.

July 1, 2007: Le Le and Ying Ying officially opened to the public at Ocean Park Hong Kong, commemorating the 10th anniversary of Hong Kong’s return to China.

Historical Context:

• September 12, 2007: China officially ceased the traditional “panda diplomacy” of gifting pandas to foreign zoos
• Le Le and Ying Ying represent one of the last panda gifts before this policy transition to cooperative research programs

Life at Ocean Park Hong Kong

Arrival and Settlement

April 26, 2007: Le Le and Ying Ying arrived at Ocean Park Hong Kong, beginning their new lives as ambassadors for the city. The pandas received a luxury habitat with premium amenities:

Habitat Features:

• High-end audio system playing recordings of natural sounds from Wolong—birdsong, flowing water, rustling leaves
• These sounds occasionally make Le Le feel as if he’s back in his Sichuan homeland
• Climate-controlled environment matching their preferred temperature range
• Customized dietary provisions including premium bamboo,窝窝头 (panda bread), and milk

Early Days: The Panda Blog

May 10, 2007: Ocean Park launched the “Panda Blog” to share updates about Le Le and Ying Ying’s life in Hong Kong. The first blog entry was written by Le Le himself, describing their “first day” in their new home:

In his blog, Le Le wrote in the casual, emoji-laden style of young people at the time, describing how they arrived at 5:30 PM and quickly explored their new enclosure. He noted that Ying Ying showed her mischievous side, climbing and exploring their new home while he was more reserved. The caretakers played recordings of flowing water and bird calls to help them adjust, and within an hour they were enjoying their first “Hong Kong-style panda meal” of bamboo, panda bread, and milk.

Learning Cantonese

The pandas were learning to understand Cantonese commands from their keepers. Despite being in a new environment with different language cues, they adapted well to their handlers’ instructions.

Breeding Journey: 13 Years of Attempts

Early Attempts (2011-2020)

2011: Le Le and Ying Ying began attempting natural mating, but success did not come immediately. Giant pandas have notoriously low mating success rates, with females only fertile for 24-72 hours per year.

April 6, 2020: The pair successfully completed their first natural mating, generating excitement among conservationists. However, this did not result in pregnancy.

The Historic Success (2024)

March 2024: Le Le and Ying Ying successfully natural mated again during the breeding season. This time, the mating took place after years of attempts and learning.

August 15, 2024: After nearly five months of pregnancy (approximately 144 days), Ying Ying gave birth to twin cubs at 2:05 AM and 3:27 AM. The twins, a female and male, became the first giant pandas born in Hong Kong.

Significance of the Birth

• Ying Ying, at approximately 19 years old, became the oldest first-time panda mother on record
• Natural mating success is rare for giant pandas in captivity
• The birth represents a major conservation milestone for the species
• The twins’ birth was celebrated throughout Hong Kong and mainland China

Post-Birth Care

The twin cubs grew rapidly under Ying Ying’s care:

• First nursing, first eye-opening, first crawling milestones documented
• Care team (nicknamed “nanny team”) observed Ying Ying’s excellent maternal instincts
• One caretaker noted: “I feel like I’ve become a grandmother”

The twins made their public debut, attracting approximately 5,000 visitors on their first day, with thousands more watching live streams.
