Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
ying minh » ying jin, yang mind
sang minh » kang minah, anh minh, song min
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
yang yi » yang di, yang jui
yang xi » yang di, yang jui

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang yang ((yang yi) OR (yang xi)) li ((ying minh) or (sang minh)) ((hong ghi) or (hong hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((yang yi) OR (yang xi)) li ((ying minh) OR (sang minh)) ((hong ghi) OR (hong hai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yang yi) OR (yang xi)) li ((ying minh) or (sang minh)) ((hong ghi) or (hong hai)) ;*".
