Perhaps you should try some spelling variations:
dong duong » tuong duong, cuong duong, dong thong
theo chieu » theo tieu, ho chieu, thi chieu
duong manh » duong van
theo chu » cho chu, chao chu, theo yeu
thanh ha » thanh hoa, thanh hai, nhanh ha
toan cau » toan ban, toan tap, toan tai
toan cao » toan ban, toan tap
ha dong » hoat dong, van dong

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: ((theo chieu) OR (theo chu)) xanh - dinh thanh ha dong duong manh ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (theo chu)) xanh - dinh thanh ha dong duong manh ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (theo chu)) xanh - dinh thanh ha dong duong manh ((toan cau) or (toan cao))*.
