Perhaps you should try some spelling variations:
hua irene » hua ren
sang minh » kang minah, anh minh, song ming
yang y.c » yang yao, yang 4.3, yang yun
yang yue » wang yue, yang yun, yang jui
song min » song ming, gong min, jong min
long shu » cong shu, tong shui, long du
yang yi » yang di, yang xi, 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: yang ((((yang y.c) or (yang yue))) or (yang yi)) hua irene ((sang minh) OR (song min)) long shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang ((((yang y.c) OR (yang yue))) OR (yang yi)) hua irene ((sang minh) OR (song min)) long shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((((yang y.c) or (yang yue))) or (yang yi)) hua irene ((sang minh) OR (song min)) long shu ;*".
