The zoo says Ya means elegant and Xi means happy. Lun is a reference to the cubs’ mother, Lun Lun.
The zoo offered online voting to let the public choose among seven sets of names supplied by a panda conservation center in Chengdu, China. Voting ran from Nov. 21 through Dec. 4, and more than 23,400 votes were recorded.
The cubs are expected to make their public debut in the coming weeks.
