Perhaps you should try some spelling variations:
thanh nhung » thanh hung, hanh nhung, tranh nhung
chiet tach » chieu sach
canh trinh » canh tranh, hanh trinh, anh trinh
nhung cong » dung cong, thong cong, hang cong
canh tinh » hanh tinh, manh tinh, canh tranh
ho chiet » ho chieu, ho thiet, hoc thiet
cong dan » cong san, cong tan, huong dan
than cao » thai cao, than cap, than sao
toan cao » toan ban, toan tap

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: ho chiet tach - ((canh trinh) OR (canh tinh)) thanh nhung cong dan ((than cao) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - ((canh trinh) OR (canh tinh)) thanh nhung cong dan ((than cao) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - ((canh trinh) OR (canh tinh)) thanh nhung cong dan ((than cao) or (toan cao))*.
