I find this funny.....while I was searching " do Chinese claim Manchus as Chinese " on some forums some Chinese claims Manchus are more Chinese than South Chinese or more South Chinese than Hakka or Cantonese. This is clearly the mindset of a Chinese who had been conquered and humiliated in the past, so in order to avoid shame they include them as Chinese.
The funny is, it was also the Hakka and Cantonese that overthrew the Qing dynasty.
