Perhaps you should try some spelling variations:
ein zugang » einen zugang, beim zugang, den zugang
wang hong » wang yong, wang hyoung, wang lihong
zugang li » zugang ii, zugang list, zugang als
wong shiu » wong siu, cong shu, song shin
kong ham » kong hang, kong sar, kong a
kong yam » kong sar
hong yu » wong yue

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang hong ((kong ham) OR (kong yam)) ein zugang li ((wong shiu) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hong ((kong ham) OR (kong yam)) ein zugang li ((wong shiu) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang hong ((kong ham) OR (kong yam)) ein zugang li ((wong shiu) or (hong yu)) ;*.
