Perhaps you should try some spelling variations:
hoc thieu » toc thieu, hoc hien
hanh manh » hanh mang, lanh manh, hoang manh
va duong » van duong, va tuong, va huong
cong tap » cuong tap, cong tac, cong tan
tap doan » tap quan
doan cau » toan cau, doan dau, doan cap
doi chi » doi khi
va dung » van dung, vat dung, va ung

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 (doi chi)) tinh - hanh manh ((va dung) OR (va duong)) cong tap doan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (doi chi)) tinh - hanh manh ((va dung) OR (va duong)) cong tap doan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (doi chi)) tinh - hanh manh ((va dung) OR (va duong)) cong tap doan cau*".
