Perhaps you should try some spelling variations:
yang quang » yang guang, yang yang
yang liang » wang liang, yan liang, yang yang
wang ning » wang jing, wang liang, wang yang
chia rene » chia wen, china ren
china who » china why, china what, china won
ning sun » nina sun, wing sun, liang sun
hong yu » wong yue

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: wang ning sun ((chia rene) OR (china who)) ((yang quang) OR (yang liang)) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ning sun ((chia rene) or (china who)) ((yang quang) OR (yang liang)) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ning sun ((chia rene) or (china who)) ((yang quang) OR (yang liang)) hong yu ;*.
