Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
trinh quan » tinh quang, trinh han
hoc thieu » toc thieu, hoc hien
cong tac » cong ty
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac
luat » luan, xuat

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

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - hanh ((trinh luat) OR (trinh quan)) trong cong tac ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh ((trinh luat) or (trinh quan)) trong cong tac ((than cau) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh ((trinh luat) or (trinh quan)) trong cong tac ((than cau) OR (than cap))*.
