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
li rong » yi rong, li cong, li song
rong yu » hong yu, rong su, wong yue
tan li » tang li, tian li, gan li
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)) tan li rong 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)) tan li rong yu ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((yan yuan) OR (yan guan)) ((di rene) or (di erence)) tan li rong yu ;*.
