It is a such sad case. Ms. Yang already divorced with her exhusband, why still live together?! She can't sacrifice everything for her son. Also, even if live together after divorce...she does not need to listen to her ex and go to cruise to HK with him. If she avoided this cruise, the tragedy maybe avoided. But the root cause is, she is too weak...after the divorce, she is NO LONGER his wife, she does not need to listen to him. Sigh. ...hope Ms. Yang rest in peace.
