Perhaps you should try some spelling variations:
juan rene » juan meng, juan rana
yang vinh » yang jin, yang jing, yang lin
sang minh » kang minah, anh minh, song min
yang y.c » yang yao, yang 4.3, yang yue
long shu » cong shu, tong shui, long du
lng 4.3 » xing 4.3, yang 4.3
yang yi » yang di, yang xi, yang jui

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: dong ((((yang y.c) OR (lng 4.3))) OR (yang yi)) juan rene ((yang vinh) OR (sang minh)) long shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((((yang y.c) or (lng 4.3))) or (yang yi)) juan rene ((yang vinh) OR (sang minh)) long shu ;~".
• Adding a wildcard symbol may retrieve word variants: dong ((((yang y.c) or (lng 4.3))) or (yang yi)) juan rene ((yang vinh) OR (sang minh)) long shu ;*.
