Perhaps you should try some spelling variations:
challenges min » challenges m, challenges making, challenges moving
3 assessment » 3 assessing
wan yanling » wang yanling, wang yangming, wang danning
min hyoung » min hong, mun young
hyoung hai » hong hai
yang yi » yang di, yang xi, yang jui
ng m » g m, n m, ng _

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wan yanling) or (yang yi))ng m ((3 assessment) OR (4 assessment)) challenges min hyoung hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yanling) OR (yang yi))ng m ((3 assessment) OR (4 assessment)) challenges min hyoung hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yanling) or (yang yi))ng m ((3 assessment) OR (4 assessment)) challenges min hyoung hai ;".
• Adding a wildcard symbol may retrieve word variants: ((wan yanling) or (yang yi))ng m ((3 assessment) OR (4 assessment)) challenges min hyoung hai ;*.
