Thank you for your question! A large number of people ordered these three things in this way: spouse first, children second and parents third. They believe that this kind of sequence is beneficial to the family harmony. However, I have different ideas in this question. Here is my analysis below:
Let's talk about the children first! If your child won't get married, the sequence should be in this way: children first, spouse second and parents third. The reason is that when the baby is born, parents should undertake the huge responsibility to their child's growth and educational investments in a long period of time, therefore the child is almost everything to our parents before adult. At the same time, we should spend more time to accompany our child in the growth stage, in order to nurture and protect our kid in a healthy condition. However, if the children get married and start his or her career, then the sequence should be reversed: spouse first, children second and parents third. In this case, our child has their own new family to organized and prepared for it, we should let our child go and spend the rest of senior lifestyle.
