Perhaps you should try some spelling variations:
done using » line using, move using
yang guang » yang yang, yang liang
ming chen » ming china, kang chen, yung chen
chen wang » chen yang, chen rong, chen ping
wang hong » wang yong, wang hyoung, wang lihong
yan guan » yan yuan, yihan guan, quan guan
gan guan » quan guan, fan guon, gui guan
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: done using ((((yan guan) OR (yang guang))) OR (gan guan)) ming chen wang hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "done using ((((yan guan) OR (yang guang))) or (gan guan)) ming chen wang hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: done using ((((yan guan) OR (yang guang))) or (gan guan)) ming chen wang hong yu ;*.
