|Locals want to protect what's left of Hong Kong's identity and institutions|
However, for many locals, this slogan would not do -- they do not want to have anything to do with China except to remember the victims of June 4 and the fact that they can do that in Hong Kong is what makes the city so special.
And so the word 本土 has been used lately to describe the invasion of mainlanders in Hong Kong and how their strong buying power has literally changed the landscape of the city: snapping up luxury goods and eating expensive foods like shark's fin and abalone, greedy landlords seeing dollar signs and kicking out mom-and-pop shops and replacing them with jewellery and watch shops paying astronomical rents.
Of course Beijing wants to make sure it wins every time and so whoever becomes CE will have to kowtow to his mainland bosses if he wants to keep his job no matter how much Hong Kongers hate him/her. The other is that the Hong Kong government is too weak or lacks any kind of integrity to make decisions on its own without consulting Beijing.
