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