Perhaps you should try some spelling variations:
tong thuong » thong thuong, trong thuong, cong thuong
chien xanh » chieu xanh, chien tranh, hien hanh
thuong dan » huong dan, thuong han, thuong dam
can chien » van chien, cac chien, tran chien
thong cua » thong quan, thong tu, huong cua
mang cua » manh cua, dung cua, ban cua
toan cau » toan cao, toan tap, toan tai
toan ban » van 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: can chien xanh - hanh ((thong cua) OR (mang cua)) tong thuong dan ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: can chien xanh - hanh ((thong cua) or (mang cua)) tong thuong dan ((toan cau) or (toan ban))*.
