Perhaps you should try some spelling variations:
chien xanh » chieu xanh, chien tranh, hien hanh
tong huong » thong huong, tong thuong, cong huong
can chien » van chien, cac chien, tran chien
thong cua » thong quan, thong tu, huong cua
mang cua » manh cua, dung cua, ban cua
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

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: can chien xanh - hanh ((thong cua) OR (mang cua)) tong huong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: can chien xanh - hanh ((thong cua) or (mang cua)) tong huong dan toan cau*.
