My 大嫂 is also come from mainland. (She have HKid now, and live in mainland).
I give her daughter 2k as 利是. It is because my brother always pay when we eat outside with my parents before he got marry. Ofcourse my brother doesn't pay for meal now (after got marry).
However, I don't like their daughter. Her heart is ........ so 'bad' (even she is only 5 years old). She always do something to hurt my kids when adults do not look at her.
