Is 16 MINUTES SUFFICIENT FOR TRANSFER from train C7638 to train G6549 at Guangzhou South railway Sta

I booked train ticket for train C7638 Zhuhai to Guangzhou South. Train arrives at Guangzhou South at 11.07 am. In addition I booked ticket for train G6549 from Guangzhou South. This train departs from Guangzhou South at 11.23 am. It means that I have 16 MINUTES FOR TRANSFER FROM TRAIN C7638 TO TRAIN G6549.
Please, is 16 MINUTES SUFFICIENT FOR THIS TRANSFER, OR NOT?
What platform does train C7638 arrive and what platform does train G6549 leave? If platforms are very close maybe it is possible.
Do anybody have any experiance with this matter?
