Perhaps you should try some spelling variations:
wang lihong » wang liang, wang shiyong
move using » done using
yihan guan » yan guan
ming chen » ming china, yung chen, ming chengzu
kang chen » chang chen, jane chen, kang han
lihong yu » hong yu
gan guan » yan guan, quan guan, fan guon

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: move using ((yihan guan) OR (gan guan)) ((ming chen) OR (kang chen)) wang lihong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "move using ((yihan guan) or (gan guan)) ((ming chen) OR (kang chen)) wang lihong yu ;~".
• Adding a wildcard symbol may retrieve word variants: move using ((yihan guan) or (gan guan)) ((ming chen) OR (kang chen)) wang lihong yu ;*.
