Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
thieu xanh » chieu xanh, hieu manh, thien anh
hoc thieu » toc thieu, hoc hien
thanh cac » hanh cac, thanh bac, thanh ca
tung cua » trung cua, tuong cua, tang cua
dung cua » dung luan, dung cho
cong dan » cong san, cong tan, huong dan
than cap » khan cap, thanh lap, than cua

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