Perhaps you should try some spelling variations:
yan yuan » fang yuan, nan yan, yan clan
yan guan » gan guan, yang guang, yihan guan
di rene » di rete, dr rene, i 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) OR (yan guan)) ((di rene) OR (di erence)) tian li cong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((yan yuan) OR (yan guan)) ((di rene) or (di erence)) tian li cong yu ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((yan yuan) OR (yan guan)) ((di rene) or (di erence)) tian li cong yu ;*.
