How common was it for Hong Kongers to keep queue haircut?

Dec 2014
Looking at old photos and illustrations of Hong Kong before 1911 it seems like there were ordinary Chinese residents who kept the Qing dynasty haircut, while photos of wealthier and 'western educated' Chinese from the same time usually have short haircuts. Does anyone know how common it would have been for ordinary Chinese in Hong Kong before Xinhai Revolution to keep this hairstyle, even if they were permanent residents with no regular reason to travel to the mainland?

Would there have been any social expectation among Hong Kong Chinese community to keep this haircut? Would keeping this haircut have shown any division among Hong Kong's community between those who considered themselves loyal to Qing vs. those who had more British loyalty?
