Why does MODERN Western philosophy use Hegel as a dividing line?

Modern Philosophy in foreign countries is generally the philosophy of the 17th to 19th centuries, and Western philosophy after the 20th century is generally called Contemporary Philosophy in foreign countries.

The so-called "Modern Western Philosophy" in mainland China is from after Hegel (1770-1831), and it should be Philosophy after Hegel if it is accurately translated into English.

The so-called "Modern Western Philosophy" in the academic circles in mainland China started after Hegel (1770-1831), which is accurately translated into English as Philosophy after Hegel.

Hegel is generally regarded as the "traditional" and "modern" philosophers of Western philosophy in mainland China.

Hegel has been widely used in mainland China as the dividing line between "traditional" and "modern" Western philosophy, and many European and American scholars have also adopted or agreed with this division. The main reason for this division is that traditional Western philosophy reached its peak in Hegel's philosophy, and he constructed a huge and unified philosophical system that included all kinds of categories and almost all important propositions in the history of philosophy. Traditional philosophy was already "complete" in his system. After Hegel, philosophy could no longer develop along the lines of the past, so Western philosophy entered a new phase of criticizing Hegel and trying to transcend traditional philosophy.

Currently, academic exchanges have been globalized, and China's is also global and influential in the world. Of course, there are many in the Western academy who use other methods of demarcation, some dividing by Frege, some by Nietzsche, and some by Heidegger. Even for those scholars who agree with the division by Hegel, their reasons are not the same.
