Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hanh trang » thanh trung, canh tranh, hanh trinh
hoc thieu » toc thieu, hoc hien
cong san » cong tac
phan cau » phan dau, phan cac, phan lap
va lang » hoa lang
va nang » van nang, da nang, cam nang

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 xanh - hanh trang ((va lang) or (va nang)) cong san ((phan cau) OR (phan tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - hanh trang ((va lang) OR (va nang)) cong san ((phan cau) OR (phan tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh trang ((va lang) or (va nang)) cong san ((phan cau) OR (phan tu))*".
