Perhaps you should try some spelling variations:
case linking » case thinking, phase linking, case finding
linking long » thinking long, linking land, linking local
yang liang » wang liang, yang yang, peng liang
yan liang » wang liang, you liang, yan wang
time case » time based, time bases, time class
dong sind » dong sin, dong bin
dong ping » dong sin, dong bin, dong jung

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan ((yan liang) OR (yang liang)) time case linking long ((dong sind) or (dong ping)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yan liang) OR (yang liang)) time case linking long ((dong sind) OR (dong ping)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan liang) OR (yang liang)) time case linking long ((dong sind) or (dong ping)) ;*".
