The growth environment is good, and it has grown into a giant panda. Chengdu Giant Panda Breeding Research Foundation (202 1-05-26) reported that Runyue and Aijiu were both born on June 5, 2020. The most striking feature of Runyue is that her hair color is yellow, and Aijiu, whose birth weight is 2 19g, is an out-and-out "fat girl". Perhaps because of the same cygnus, this pair of "September combination" has an unusual tacit understanding with each other.
