Perhaps you should try some spelling variations:
ren xiaodong » lin xiaodong, wang xiaodong, du xiaodong
hong cheng » hong sheng, zong cheng, hoong chang
ong cheng » zong cheng, ong chong, dong sheng
wen fang » weng fang, wen wang
yin fang » yin hang, yin yang, chin fang
ke dang » le dang
hai » hadi, haji, hari

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: ren xiaodong ((hong cheng) OR (ong cheng)) ((wen fang) OR (yin fang)) ke dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ren xiaodong ((hong cheng) OR (ong cheng)) ((wen fang) or (yin fang)) ke dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ren xiaodong ((hong cheng) OR (ong cheng)) ((wen fang) or (yin fang)) ke dang hai ;*.
