Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu tinh » trieu tinh, lieu tinh, chau tinh
tranh cua » doanh cua, manh cua
cua nhung » va nhung
cong dan » cong san, cong tan, cong dong
phan cac » nhan cach, phan lap, phan van
phan dau » phan tu, hang dau

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 chieu tinh - canh tranh cua nhung ((cong dan) OR (huong dan)) ((phan cac) OR (phan dau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - canh tranh cua nhung ((cong dan) OR (huong dan)) ((phan cac) or (phan dau))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - canh tranh cua nhung ((cong dan) OR (huong dan)) ((phan cac) or (phan dau))*.
