Perhaps you should try some spelling variations:
phung cong » nhung cong, phong cong, nhung chong
hoc thieu » hoc hien
nhan thuc » nhan luc, dan thuc
toan thuc » toan hoc, dan thuc
cong than » cong thanh, cong thang, cong tan
than nhan » thanh nhan, than phan, chan nhan
nhan cach » phan cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc thieu) OR (toc thieu)) anh - tinh ((nhan thuc) or (toan thuc)) phung cong than nhan cach~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (toc thieu)) anh - tinh ((nhan thuc) OR (toan thuc)) phung cong than nhan cach*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (toc thieu)) anh - tinh ((nhan thuc) or (toan thuc)) phung cong than nhan cach*".
