sang minh » kang minah, anh minh, song min
minh long » minh cong, vinh long
yang y.c » yang yao, yang 4.3, yang yue
hua rene » hua ren, juan rene
long shu » cong shu, tong shui, long du
yang yi » yang di, yang xi, yang jui

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang y.c) OR (yang yi)) hua rene sang minh long shu ;*".
