Perhaps you should try some spelling variations:
hang cong » dang cong, hang nong, bang cong
nhanh cau » nhanh cay, thanh chau, nhanh ha
chi danh » chi dan, chi anh, chi dinh
dung cua » dung luan
cong cac » cuong cac, cong tac, cong cau
nhan cau » phan cau, nhan sau, nhin cau
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 danh - thanh ((dung cua) OR (dung cho)) hang cong cac ((nhan cau) OR (nhanh cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi danh - thanh ((dung cua) OR (dung cho)) hang cong cac ((nhan cau) or (nhanh cau))~".
• Adding a wildcard symbol may retrieve word variants: doi chi danh - thanh ((dung cua) OR (dung cho)) hang cong cac ((nhan cau) or (nhanh cau))*.
