Perhaps you should try some spelling variations:
thieu manh » hieu manh, tien manh, trieu minh
hanh trang » thanh trung, canh tranh, hanh trinh
hoc thieu » toc thieu, hoc hien
tuan dung » tuan duong, tran dung, tuan dang
tan dung » tran dung, tin dung, van dung
cong san » cong tac
toan cau » toan ban, toan tap, toan tai
toan cao » toan ban, toan tap

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 manh - hanh trang ((tuan dung) or (tan dung)) cong san ((toan cau) OR (toan cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu manh - hanh trang ((tuan dung) OR (tan dung)) cong san ((toan cau) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu manh - hanh trang ((tuan dung) or (tan dung)) cong san ((toan cau) OR (toan cao))*".
