Perhaps you should try some spelling variations:
huong manh » duong manh, hung manh, luong manh
chua xang » chuc nang, chu bang, chua dong
chua nang » chuc nang, kha nang, cuu nang
canh manh » lanh manh, canh tranh, cach mang
manh toan » thanh toan, anh tuan, tinh toan
cua dung » cua dang, cua dong, qua dung
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: theo ((chua xang) OR (chua nang)) - canh manh ((cua dung) OR (cua ban)) huong manh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua xang) OR (chua nang)) - canh manh ((cua dung) or (cua ban)) huong manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chua xang) OR (chua nang)) - canh manh ((cua dung) or (cua ban)) huong manh toan cau*.
