Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
thi chieu » thi chien, thi hieu, theo chieu
canh manh » lanh manh, cach mang, van manh
cua nhung » va nhung
ho chieu » theo chieu, hoc thieu, doi chieu
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh
toan ban » van ban

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 chieu) OR (thi chieu)) sang - ((canh manh) OR (canh tranh)) cua nhung cong van toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (thi chieu)) sang - ((canh manh) OR (canh tranh)) cua nhung cong van toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (thi chieu)) sang - ((canh manh) OR (canh tranh)) cua nhung cong van toan ban*.
