Perhaps you should try some spelling variations:
when cluding » when studying, when using, when adding
dong sind » dong sin, dong bin, dong ping
best when » bent when, best what, debt when
zhong zhi » zhang zhi, zhong tai
wing ian » wing tan, twinn ian, wing sun
der best » der besitz
hong ghi » hong g, hong hai
ya der » aa der

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: ((wing ian) OR (dong sind)) ya der best when cluding ((hong ghi) OR (zhong zhi)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((wing ian) or (dong sind)) ya der best when cluding ((hong ghi) or (zhong zhi)) ;*.
