Perhaps you should try some spelling variations:
doanh hoan » doanh doanh, doanh khoa, doanh nhan
hanh doanh » hang doanh, chinh doanh, doanh doanh
duong manh » duong van
han duong » hai duong, van duong, thanh duong
manh toan » thanh toan, anh tuan, tinh toan
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
toan ban » van ban
tai han » tai phan, tai san, dai han

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 chu xanh - ((hanh doanh) OR (doanh hoan)) tai han duong manh toan ban~.
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((hanh doanh) or (doanh hoan)) tai han duong manh toan ban*.
