The ideal family is relative to the individual that pursues it. There are too many different groups of people in this world, so having one standard for the ideal family will not work.
An example of an ideal family is the White Picket Fence American Dream. The American Dream pictures a successful middle class, loving family in a nice suburban neighborhood. This is still pursued by some Americans. However, it almost has nothing in common with an ideal family in China.
An ideal family in China is centralized around the lineage of the family. The stronger the ties are between the son and father, the closer it resembles an ideal family.
