Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
mot chieu » doi chieu, ho chieu
tranh cua » doanh cua, manh cua
cua nhung » va nhung
cong manh » cong danh, duong manh, cong thanh
toan cao » toan ban
toan tap » toan ban

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: ((mot chieu) OR (toc thieu)) xanh - canh tranh cua nhung cong manh ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (toc thieu)) xanh - canh tranh cua nhung cong manh ((toan cao) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (toc thieu)) xanh - canh tranh cua nhung cong manh ((toan cao) OR (toan tap))*.
