Perhaps you should try some spelling variations:
reformen bei » reformen beim, reformen teil, reformen der
li reformen » die reformen, iii reformen, 1 reformen
david dang » david ian, david mant, david ng
you qiang » you liang
you xian » you liang, you can, you mean
david n » david a, david _, david k

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: warn ((you qiang) OR (you xian)) li reformen bei ((david dang) OR (david n)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "warn ((you qiang) OR (you xian)) li reformen bei ((david dang) or (david n)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: warn ((you qiang) OR (you xian)) li reformen bei ((david dang) or (david n)) hai ;*.
