    What are the components in the voltage divder bias circuit that make BJT work in saturation mode from active mode?
    I just guess that Rc, Re could cause saturation but don't know exact reason.

    It is all about the load line. Once you have the endpoints, you can place the quiescent point.

    Umm....I wonder if saturation will occur when resistance value of Rc and Re increased

    It's their ratio as well as their absolute value that determines the bias point.
