.....need to apply China Visa in their home-country now, if they are not holding HK - ID card:
Afghanistan / Algeria / Bangladesh / Congo / Egypt / Gambia / Ghana / Guinea / India / Indonesia / Iran / Iraq / Kaiakhstan / Kirghiziani / Libya / Malaysia / Mali / Mauritania / Monaco / Nepal / Nigeria / Pakistan / Philippines / Saudi Arabia / Sierra Leone / South Africa / Sri Lanka / Sudan / Syrian / Tajikistan / Tunisia / Turkey / Uzbekistan
In regards of ID card - probably it is meant "permanent ID card".
