Perhaps you should try some spelling variations:
yang ying » yang yang, yang jing, huang ying
wang yong » wang yang, wang hyoung, wang yan
hua irene » hua ren
sang minh » kang minah, anh minh, song min
jeong shu » jeong su, cong shu
tang min » chang min, yang mind, tang li
tan li » tang li, tian li, gan li

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang ying) or (wang yong)) ya hua irene ((tan li) or (((sang minh) OR (tang min)))) jeong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang ying) OR (wang yong)) ya hua irene ((tan li) OR (((sang minh) OR (tang min)))) jeong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang ying) or (wang yong)) ya hua irene ((tan li) or (((sang minh) OR (tang min)))) jeong shu ;*".
