Big sister, Jiayu; A-mei, Jia Jia; Little sister, Jialing. But it seems to be a stage name, and from the height and voice, Jia Jia seems to be older than Jia Yu. But Jiayu is more like a big sister. I really like the three sisters of plum blossom. Although I'm not from Taiwan Province Province, I'm from Shantou, and I like Jiayu best, with a rich expression.
