Perhaps you should try some spelling variations:
thuat lanh » thuat lap, thuat san
lanh kha » lang kham, lanh nham, manh khai
kha nang » phap nang, ky nang, ki nang
hieu van » thien van, lieu va
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, va danh
vi luu » vi lua
tru » truc

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh kha nang xa hoi. ((((hieu ve) OR (hieu van))) or (hieu va)) pham duc va hanh vi luu tru~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh kha nang xa hoi. ((((hieu ve) OR (hieu van))) OR (hieu va)) pham duc va hanh vi luu tru.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh kha nang xa hoi. ((((hieu ve) OR (hieu van))) or (hieu va)) pham duc va hanh vi luu tru".
• Adding a wildcard symbol may retrieve word variants: thuat lanh kha nang xa hoi. ((((hieu ve) OR (hieu van))) or (hieu va)) pham duc va hanh vi luu tru*.
