Perhaps you should try some spelling variations:
lang yan » wang yan, wang yang, zhang yan
yan yuan » yan guan, fang yuan, nan yan
dii rene » iii rene, dr rene, i rene
ii rene » iii rene, i rene, wie rene
tian li » tan li, kian lia
li cong » li rong, li song, jiu cong
cong yu » hong yu, rong yu, chong yun
erence » terence, terrence

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 yuan ((((dii rene) OR (ii rene))) OR (di erence)) tian li cong yu ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan yuan ((((dii rene) or (ii rene))) or (di erence)) tian li cong yu ;*.
