I'm pretty sure they're full brothers and it's insane. Myolie Wu is way too young for this nonsense. I love her…
Yes. It's so unfair for female actresses. I don't understand this kind of casting also. I have seen quite a few Cdramas with the moms like 15 years older or less than her son or daughter in real life. This is the smallest age gap so far that i noticed.
