uprising together with Germans against russia invasion, and it garnered sympathy from many Chinese people --- though Polish people are anti-Chinese for religious and communism (maybe also religious) reasons
I don't think there's any such sentiment in Poland; in fact, this research points to (slightly) positive sentiment of the Polish towards the Chinese: https://www.cbos.pl/SPISKOM.POL/2026/K_016_26.PDF
Maybe you've been confused by some of the resistance fighters wearing German helmets?
The Germans crushed the uprising because the Soviets conveniently stopped their advance, giving the Germans time to focus on the Polish resistance, which was convenient for the Soviets because it eliminated a potential "problem" for the Soviet occupation of Poland after WW2.
