臺北市立動物園
Yuan Yuan gave birth to a cub on July 6, 2013 at the Taipei Zoo. The female cub was nicknamed Yuan Zai (also pronounced in Taiwanese Hokkien as Inn-a). Yuan Zai has several meanings: rice ball, and also '(Yuan)Yuan's child'. On October 26, at the zoo's 99th anniversary ceremony, the baby panda was officially named Yuan Zai after a naming activity that saw 60% of the votes go to the cub's nickname. She was also presented an honorary citizen's card on that day. As Tuan Tuan and Yuan Yuan were sent to Taiwan in exchange for two Formosan sika deer and two Taiwan serows, the cub does not need to be returned.
