Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu, hoc hien
trinh hoa » trinh do, trinh han
trinh ha » trinh han, trinh nha, trinh he
tac doan » tan doan, thai doan, cac doanh
tap doan » tap quan

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 ha) OR (trinh hoa)) nhung cong ((tac doan) OR (tap doan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh ((trinh ha) OR (trinh hoa)) nhung cong ((tac doan) or (tap doan)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh ((trinh ha) OR (trinh hoa)) nhung cong ((tac doan) or (tap doan)) cau*.
