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