Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu
cong danh » cuong danh, cong dan, cong thanh
danh toan » manh toan, anh toan, dan toan
trung ve » trung va, trung vi, trung vo
trung vu » trung va, truong va, trung ha
toan ban » van ban

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc hien) or (hoc thieu)) manh - hanh ((trung ve) OR (trung vu)) nhung cong danh toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc hien) OR (hoc thieu)) manh - hanh ((trung ve) OR (trung vu)) nhung cong danh toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hien) or (hoc thieu)) manh - hanh ((trung ve) OR (trung vu)) nhung cong danh toan ban".
• Adding a wildcard symbol may retrieve word variants: ((hoc hien) or (hoc thieu)) manh - hanh ((trung ve) OR (trung vu)) nhung cong danh toan ban*.
