Perhaps you should try some spelling variations:
di terrence » di erence, deal terrence
lang yan » wang yan, wang yang, zhang yan
yan guan » gan guan, yan yuan, yang guang
der rent » der re, der rede
song yun » song byung, chong yun, young yun
tian yi » qian yi, tian yu, tan yi
yi song » yi rong, li song, kim song

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: lang yan guan ((((dr rene) OR (der rent))) OR (di terrence)) tian yi song yun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan guan ((((dr rene) OR (der rent))) or (di terrence)) tian yi song yun ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan guan ((((dr rene) OR (der rent))) or (di terrence)) tian yi song yun ;*.
