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
cong dan » cong san, cong tan, huong dan
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac
tung va » trung va, tuong va, vung va

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 - manh ((tung va) OR (dung va)) nhung cong dan ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - manh ((tung va) OR (dung va)) nhung cong dan ((than cau) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - manh ((tung va) OR (dung va)) nhung cong dan ((than cau) or (than cap))*.
