Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
dan yang » daun yang, tan yang, yang yang
zhi test » ai test, i test, ii test
api test » ai test, i test, ii test
yang jie » yang jin, yang di, yang jui
yang lin » yang jin, wang lin, yang li
hong yu » wong yue

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((dan yang) or (wang yang)) wang ((zhi test) OR (api test)) ((yang jie) or (yang lin)) hong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dan yang) OR (wang yang)) wang ((zhi test) OR (api test)) ((yang jie) OR (yang lin)) hong yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dan yang) or (wang yang)) wang ((zhi test) OR (api test)) ((yang jie) or (yang lin)) hong yu ;".
• Adding a wildcard symbol may retrieve word variants: ((dan yang) or (wang yang)) wang ((zhi test) OR (api test)) ((yang jie) or (yang lin)) hong yu ;*.
