After a series of disqualifications of the Cantonese running for the council and parliamentarians over the past number of years, I believe that the Hong Kong people already view the legislative council as merely a puppet council of the Chinese government because the Hong Kong people cannot enjoy the right of electing their representation fairly.
For me, yes indeed, its legitimacy is largely challenged and Hong Kong people believe less and less in the change in the system, and that is why protests broke out so massively last year because they stopped believing in participating in the system that had made a concrete change.
