Perhaps you should try some spelling variations:
guan guan » quan guan, gui guan, yan guan
guan rene » juan rene, glas rene
wong shiu » wong siu, cong shu, song shin
lang gan » lang lang, lang a, qing gan
gan guan » yan guan, quan guan, fan guon
yang jin » yang jie, yang jun, ying jin
yang xi » yang yi, yang jui
sin » sign, sind, skin

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "lang gan guan guan rene ((((yang jin) OR (yang xi))) OR (yang di)) ((wong shiu) OR (dong sin)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang gan guan guan rene ((((yang jin) OR (yang xi))) OR (yang di)) ((wong shiu) OR (dong sin)) ;*.
