Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
wang yang » wang yan, wang liang, wang yanling
tang minh » sang minh, kang minah, tuan minh
jeong 情 » jeong _, jeongui 情, jeong mi
iii rene » ii rene, iii reale, iii rep
iii gene » iii gender, iii genome, i gene
tang min » chang min, sang minh, yang mind

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: wang yang guang ((iii rene) OR (iii gene)) ((tang min) OR (tang minh)) jeong 情 ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang guang ((iii rene) OR (iii gene)) ((tang min) or (tang minh)) jeong 情 ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang guang ((iii rene) OR (iii gene)) ((tang min) or (tang minh)) jeong 情 ;*.
