Chinese citizen with resident of the Netherlands

Hi, I am a Chinese with resident of the Netherlands. I bought the return flight tickets from Netherlands to Shanghai in next February. In that period I want to visit Hong kong. I see some information in the web that we can have 7 days free enter Hong kong without a visa if we have Dutch ID. But my tickets have no relation with Hong kong. So I want to ask in this situation, can i have the permission to enter Hoing kong or I still need to apply for any HK type? PS: I have no exit permits to enter Hong Kong in PRC.
