Perhaps you should try some spelling variations:
va thieu » va thiet, va hieu, va tieu
hanh vai » hanh va, hanh tai, hanh van
de tang » le tang, de dang, do tang
tu cach » tu cac
tang xa » trang xa, tang ma, lang xa
ve cao » ve bao, ve cac, ve co
suc va » duc va, tuc va, luc va
va cao » va cac, va co, va dao

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cach de tang xa hoi. hieu ((ve cao) or (va cao)) suc va ((hanh vai) OR (hanh vi)) va thieu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cach de tang xa hoi. hieu ((ve cao) OR (va cao)) suc va ((hanh vai) OR (hanh vi)) va thieu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cach de tang xa hoi. hieu ((ve cao) or (va cao)) suc va ((hanh vai) OR (hanh vi)) va thieu".
• Adding a wildcard symbol may retrieve word variants: tu cach de tang xa hoi. hieu ((ve cao) or (va cao)) suc va ((hanh vai) OR (hanh vi)) va thieu*.
