Perhaps you should try some spelling variations:
liang tan » liang dan, liang sun, wing tan
gang tan » tang tang, hong tan, kang tae
wan yan » wang yan, nan yan, wai yan
guan li » gan li, yuan li, yuan lin
yang li » yang lin, yang di, yang xi
hong yu » wong yue
yan li » yuan li, gan li, tan li

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: wan yan ((((yan li) OR (guan li))) OR (yang li)) ii ((gang tan) OR (liang tan)) hong yu ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan ((((yan li) or (guan li))) or (yang li)) ii ((gang tan) or (liang tan)) hong yu ;*.
