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
trung cua » truong cua, trung tuan, trung cap
thanh lap » thanh san, phan lap, thanh hai
tung cua » tuong cua, dung cua, tang cua
cong dan » cong san, cong tan, huong dan
than cau » toan cau, phan cau, than cap

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