Perhaps you should try some spelling variations:
thanh tung » thanh cong
hien lang » hieu lang, tien lang, hien trang
cong manh » cong danh, duong manh, cong thanh
doi hien » doi dien, doi bien, doi kien
dap dung » ap dung, dan dung, dap ung
van dung » van dong, xay dung, tin dung
toan cau » toan ban, toan tap, toan tai
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: doi hien lang - thanh tung ((dap dung) OR (van dung)) cong manh ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi hien lang - thanh tung ((dap dung) or (van dung)) cong manh ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: doi hien lang - thanh tung ((dap dung) or (van dung)) cong manh ((toan cau) OR (toan cao))*.
