Perhaps you should try some spelling variations:
gene sang » lee sang, gene bank
wang jing » wang ning, wang liang, wang yang
min jeong » kin keong, min hong, mun leong
jeong ghi » hong ghi, jeong mi
sang min » sang minh, song min, tang min
tan zhi » yan zhi, wang zhi, tan chia
yuan zi » yuan li, yuan fei, yuan hui
yan zi » yan zhi, ban zi

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 jing ((tan zhi) OR (((yan zi) OR (yuan zi)))) gene sang min jeong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang jing ((tan zhi) or (((yan zi) OR (yuan zi)))) gene sang min jeong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: wang jing ((tan zhi) or (((yan zi) OR (yuan zi)))) gene sang min jeong ghi ;*.
