a trip of giant panda cubs have been formally named on the 100th day after their birth at a breeding center in the northwestern city of xi'an on november 11.
the three baby bears include a pair of twins delivered by a panda named 'zhuzhu', as well as a female cub born to her mom 'lousheng' earlier in the summer at the qinling giant panda breeding and research base under the shaanxi academy of forestry.
