Perhaps you should try some spelling variations:
tuong cong » truong cong, trong cong, tong cong
canh trang » canh tranh, hanh trang, banh trang
gioi chau » gioi cau, nguoi chau, gian chau
trang va » tran van, hang va
va tuong » va thuong, va thong, xa truong
cong tac » cong ty
phan dau » hang dau
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) OR (gioi chau)) tinh - canh trang va tuong cong tac ((phan dau) OR (phan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chi) or (gioi chau)) tinh - canh trang va tuong cong tac ((phan dau) OR (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: ((doi chi) or (gioi chau)) tinh - canh trang va tuong cong tac ((phan dau) OR (phan tu))*.
