Perhaps you should try some spelling variations:
di terrence » di erence, deal terrence
zhang yan » zhang fan, zhang jian, wang yan
song bing » song ming, song byung, dong bin
yan yuan » yan guan, fang yuan, nan yan
di rene » dr rene, i rene, ii rene
tian li » kian lia
tan li » tang li, gan li, tan yi

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: zhang yan yuan ((((di rene) OR (di rete))) OR (di terrence)) ((tian li) OR (tan li)) song bing ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang yan yuan ((((di rene) or (di rete))) or (di terrence)) ((tian li) OR (tan li)) song bing ;~".
• Adding a wildcard symbol may retrieve word variants: zhang yan yuan ((((di rene) or (di rete))) or (di terrence)) ((tian li) OR (tan li)) song bing ;*.
