Perhaps you should try some spelling variations:
thanh tinh » thanh binh, nhanh tinh, than kinh
cuong danh » cuon danh, huong dan, cuong linh
chi xanh » chi anh, chi danh, chi hanh
cua dung » cua dong, qua dung, cua rung
cua dang » cua cong, cua ban
cong dan » cong san, cong tan, huong dan
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 - thanh tinh ((cua dung) OR (cua dang)) ((cong dan) OR (cuong danh)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi xanh - thanh tinh ((cua dung) OR (cua dang)) ((cong dan) or (cuong danh)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - thanh tinh ((cua dung) OR (cua dang)) ((cong dan) or (cuong danh)) toan cao*.
