Tensions have also sharpened on university campuses between Hong Kong students, many of whom participated in the protests, and their mainland counterparts, who now make up a sizeable portion of student bodies.
Elections for the student union at the elite University of Hong Kong turned into a slanging match, when a Chinese student was accused of being a Beijing spy and subjected to personal attacks.
A student at City University, Timson Kwok, gave up his student union campaign during last year's demonstrations, telling Next magazine in an interview that two people who hinted they were working on behalf of Beijing, had offered him money and power to help "de-radicalize" the Hong Kong Federation of Students, a major force in the protests.
Kwok and City University declined to comment. China's Hong Kong Liaison Office did not respond to a request for comment.
Last chance for a direct vote?
Hong Kong is now moving towards a crucial legislative vote in late June or early July on a new electoral package for a 2017 leadership election that could allow a direct vote, but only for candidates pre-screened by a pro-Beijing committee.
Democratic lawmakers who hold a one-third veto bloc in the 70-seat legislative have vowed to vote the package down.
Sources with ties to Chinese officials dealing with Hong Kong affairs say China remains unpersuaded of the case for granting greater democratic latitude.
"Even if there's a 0.1 percent risk, Beijing won't want to take that risk of having someone elected who is against the Central Government," said one source.
A veto of the reform package would return Hong Kong to the status quo, with no direct vote for its leader.
"Unless we can resolve this conflict between Beijing and Hong Kong ... not only will we not get universal suffrage," said Ronny Tong, a moderate democratic lawmaker. "But I fear that there will be an unhappy ending to one country, two systems."
Meanwhile, on the streets, activists say the umbrella movement is far from over.
"More people will call for independence," said Tony Lam, a 32-year-old at the New Town Plaza protest in a wheelchair. "Only Hong Kong people can save Hong Kong ... That's why I keep coming out."
