Perhaps you should try some spelling variations:
reformen juan » reformen und, reformen von, reformen aus
reformen a » reformen _, reformen 2, reformen 6
david hong » david ng
warn you » earn your, can you, when you
xian wei » xiang wei, liang wei, han wei
hong ghi » zhong zhi, hong g, hong hai
wan you » want you, can you, win you

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 you) OR (warn you)) xian wei ((reformen juan) OR (reformen a)) david hong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan you) OR (warn you)) xian wei ((reformen juan) or (reformen a)) david hong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan you) OR (warn you)) xian wei ((reformen juan) or (reformen a)) david hong ghi ;*.
