Perhaps you should try some spelling variations:
cong danh » cuong danh, cong dan, cong thanh
danh toan » manh toan, anh toan, dan toan
chi xanh » chi anh, chi danh, chi hanh
cua dung » cua dong, cua rung, cua nhung
cua dang » cua cong, cua ban
qua dung » quang dung, su dung, qua song
toan cao » toan ban, toan tap
doi chi » doi khi

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 chi xanh - canh tranh ((((cua dung) OR (cua dang))) OR (qua dung)) cong danh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi xanh - canh tranh ((((cua dung) OR (cua dang))) or (qua dung)) cong danh toan cao~".
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - canh tranh ((((cua dung) OR (cua dang))) or (qua dung)) cong danh toan cao*.
