Panda Cheng Lang: The Lightest Panda Cub Ever Recorded

Panda Cheng Lang

Cheng Lang (成浪/Chenglang), born on June 11, 2019, at the Chengdu Research Base of Giant Panda Breeding, began her life against the odds. Weighing only 42.8 grams at birth – just a quarter of the weight of a typical cub—she faced early challenges that required constant care. Despite these hurdles, Cheng Lang grew stronger and healthier under the watchful eyes of her keepers, and today, she thrives at the Dujiangyan Panda Valley, alongside her twin sister, Cheng Feng.

Basic Information

Growth Experience of Panda Cheng Lang

Early Challenges: Cheng Lang was born with just a quarter of the weight of a typical giant panda cub and less than two-thirds the length of her twin sister, Cheng Feng. Her low birth weight put her in a critical condition during the first few days, requiring 24-hour monitoring. Initially unable to nurse from her mother, Cheng Lang was fed artificially with milk from her mother, although the initial feeding bottle had too large a nipple hole, causing some issues. Experts created a specially designed smaller nipple and adjusted feeding techniques to ensure her safety.

Healthy Development: Under the careful care of the panda base’s expert team, Cheng Lang gradually adapted to her environment and began nursing from her mother independently within two weeks of birth. Her health indicators improved over time, and she has grown into a sweet and healthy giant panda, catching up with her peers in all aspects of development.

Current Residence: Cheng Lang now lives at the Dujiangyan Panda Valley. On April 21, 2022, she moved there with her twin sister Cheng Feng and another panda named Ji Xiao (绩笑), starting a new chapter in her life.
