Perhaps you should try some spelling variations:
reformen im » reformen _, formen im, reformen der
liang tan » liang dan, liang sun
qian yan » qian jun, qian yi
wing tan » wing ian, hong tan, tin tan
im david » kim david, lam david, die david
david ng » david g, david n, david a
wan yan » wang yan, nan yan, wai yan
ng g » g g, n g, ng _

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: ((wan yan) OR (qian yan)) ((wing tan) OR (liang tan)) reformen im david ng g ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) or (qian yan)) ((wing tan) OR (liang tan)) reformen im david ng g ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yan) or (qian yan)) ((wing tan) OR (liang tan)) reformen im david ng g ;*.
