Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
wang yang » wang yan, wang liang, wang yanling
liang his » liang li, liang zhi
thin jeng » thin end
thin lens » thin line, thin end
dong sind » dong bin, dong ping
his last » als last, his host, his land

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang yang liang his last ((thin jeng) OR (thin lens)) ((dong sin) or (dong sind)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang liang his last ((thin jeng) OR (thin lens)) ((dong sin) OR (dong sind)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang liang his last ((thin jeng) OR (thin lens)) ((dong sin) or (dong sind)) ;*".
