Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
yan guan » gan guan, yan yuan, yihan guan
san minh » sang minh, tuan minh, anh minh
long shu » cong shu, tong shui, long du
wang hui » wang hua, wang zhi, wang wei
yang li » yang lin, yang di, yang xi
di san » de san, li san, di santa
li di » ji di, li li, li yi

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: ((yang guang) OR (yan guan)) yang li di san minh ((long shu) OR (wang hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang guang) OR (yan guan)) yang li di san minh ((long shu) or (wang hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang guang) OR (yan guan)) yang li di san minh ((long shu) or (wang hui)) ;*.
