Hi thanks for asking. Unfortunately, I'm not well-versed in China's sociology. As such, I can't comment on the "cultural status." That said, I think Confucianism is currently the dominant social ideology at the moment. Yes, Buddhism has made a great impact on the later developments of Confucianism. But with my engagement with Chinese scholars, Buddhism has pretty much been put into the category of "religion," rather than philosophy or culture, i.e. it's often omitted in political, social, and philosophical discourse.
