Super glue is one of the worst glue in the market. It is the shame to waste the words SUPER and GLUE for it.
It has very little gluebility.
On the other hand, Epoxy is very strong. When fully stablized, it could be stronger than the original matterial. You must pay attention for how long for the Epoxy to become "dry". Some epoxy is labeled for 5 minute and/or 60 minutes, but that period only makes epoxy not sticky to your fingure.
Therefore, I usually wait two days to let epoxy to dry. Afterwards, it becomes very strong.
Good luck. Epoxy is called 环氧树脂， 用同等分量的树脂(resin)和干固剂(hardener)拌匀后，涂在断裂处，等候两天就行了。
