People's three views are formed by social background, growth experience, education and other factors. It is generally believed that in middle school, it is an important period to form a person's three views, and of course it may also be changed because of some things in later life.

Three views is an important factor in making friends, which means the same as the old saying "bitter". Boyfriend and girlfriend are close friends, so whether two people have the same three views can also determine whether their feelings will go far.
