Perhaps you should try some spelling variations:
wang yidan » wang yan
yidan wang » yiqian wang, qian wang, yan wang
sang minh » kang minah, anh minh, song ming
jeong ghi » hong ghi, jeong mi
gong min » jong min, gong meng, song ming
song min » song ming, jong min, song jin
hua ren » hua chen

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 yidan wang hua ren ((((gong min) OR (song min))) OR (sang minh)) jeong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yidan wang hua ren ((((gong min) OR (song min))) or (sang minh)) jeong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: wang yidan wang hua ren ((((gong min) OR (song min))) or (sang minh)) jeong ghi ;*.
