 The question about ancient Chinese philosophy is that whether there is ancient Chinese philosophy at all. If philosophy is about what is truth, what knowledge so on and for....... then ancient Chinese ideology cannot be consider as philosophy as they are not bothered by these questions in the first place. Take Being as an example. Philosophers metaphysically debated it over centuries, metaphysically, epistemologically (you named it, they have it). But for ancient Chinese ideology, being is being by being. As long as you are breathing, you are being. Simple as that, no need to get into endless discussion especially when you cannot even provide indisputable proof regarding the metaphysic aspect of thinking.

Thus, the main concern of ancient Chinese ideology is always about how to be instead of what is be (And politics ultimately affect every how is to be). That is why all ancient Chinese ideology has strong political aspect as it core, and its metaphysical aspect is only a precondition which is not really concerning(An evidence to this is that many ideologies use the word 道dao, which means the way by the way to denotes its metaphysical aspect but didn't put in effort explaining it and we have to help them construct their theory metaphysically). Although after Wei-Jin Era, ideology is more "philosophific" due to 玄學, and buddhism plus the rise of neo-confucianism during song dynasty, whether it can be philosophy is still highly debatable.
