Perhaps you should try some spelling variations:
peng liang » wang liang, yang liang, deng ziliang
liang lili » liang lilin, ing lili, liang li
lang yang » wang yang, yang yang, lang lang
yang peng » wang peng, yang yang, ting peng
yan minh » tuan minh, sang minh, yang mind
hong shu » tong shui, wong shiu, hong seo
gong hui » tong hui, tong shui, wang hui

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: lang yang peng liang lili yan minh ((((hong shu) OR (cong shu))) OR (gong hui)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yang peng liang lili yan minh ((((hong shu) or (cong shu))) or (gong hui)) ;*.
