The people who run the government are communists. But that label does not by itself define what each individual in the party believes.
I think the majority of the Chinese people are proud of their country and will form a somewhat united front in the face of external opposition, whether they are in the communist party or not. (I say "somewhat" because there is seldom a case where everyone in a large group is in agreement with the leadership on any matter.)
As for calling them national socialists, that seems confusing to me. The Nazi party did not claim to adhere to Marx.
It’s irrelevant what the national socialist party claimed to adhere to, but what they did in practice. Josef Goebbels openly described the NSDAP as “the German Left … we despise bourgeois nationalism”; and this gives a good insight into the CPC’s strategy, where they openly tout “socialism with Chinese characteristics”, an open declaration of national socialism if there ever was one. Adolf himself in an interview expounded on point number 13 of the party’s 25-point program as “the nationalization of all public companies—in other words socialization, or what is known here as socialism”.
National socialism also migrated to the Islamic sphere of the Middle East and north Africa; the Ba’ath Party particularly openly declares itself both nationalist and socialist, and Nasser did also with his own Nasserism.
(BTW, I was just looking at Sky News’ live feed as I was typing this, and one scene showed Hong Kong’s airport with the word “Chinazi” scrawled on a display.)
