The Four Happy Meatballs

On June 23, 2019, something extraordinary happened at Chongqing Zoo: two female pandas gave birth to twins on the same day — a first in the zoo’s 60-year history.

• Lan Xiang (兰香) gave birth to twin males: Shuang Shuang (双双) and Chong Chong (重重)
• Mang Zai (莽仔) gave birth to twin females: Xi Xi (喜喜, the elder) and Qing Qing (庆庆)

A global naming contest was launched, and the four cubs were named through public voting — together becoming the “Four Treasures” (四宝) or more affectionately, the “Four Happy Meatballs” (四喜丸子). The names 双双、重重、喜喜、庆庆 together form “双重喜庆” (Double Happiness Celebration).

Enrichment Stars

The Four Meatballs became internet sensations for their creative enrichment activities. Under the careful design of their keepers, they have been seen:

• “围炉煮茶” (Sitting around a stove drinking tea) — arranged with bamboo tables and cups
• “搓麻将” (Playing mahjong) — positioned around a miniature mahjong table

These staged interactions delighted visitors and became viral hits on social media.

Life at Chongqing Zoo

Xi Xi was cared for by zoo staff 24/7 during her early months, growing from a tiny cub to a healthy weight of 4,013 grams by her 100-day checkup. She and the other three cubs were exhibited at the nursery during scheduled viewing hours.
