It can be said that the metaphors of "showing great ambitions" and "showing great ambitions" are different.

(2) "Ambition" and "Hongtu" are a pair of words with different shapes, which both mean lofty ideas or grand plans. "Hongtu" is written in a conventional way, called orthostyle, and is a recommended word form; while "Hongtu" is written in an unconventional way, called variant form, and is a non-recommended word form. But usually the Feng Shui mirrors hung in people's houses are all in the style of "Great Exhibition", with a large eagle spreading its wings on the mirror. This is more a matter of writing habits. In actual application, "showing great ambitions" is the preferred way of writing.
