Starting Oct. 9, the public will be able to vote for their favorite names for the pair through \"Good Morning America\'s\" website. Voters can chose from five sets of names selected by Zoo Atlanta colleagues at the Chengdu Research Base of Giant Panda Breeding in China: Mei Lun and Mei Hua, Mei Lun and Mei Huan, Tian Lun and Tian Le, Lan Tian and Bi Shui, or Da Lan and Xiao Lan. Results of the poll were to be announced Oct. 23 when the cubs are 100 days old.
