Perhaps you should try some spelling variations:
hanh trinh » canh tranh
nang cong » nang song, dang cong, bang cong
ho nhieu » hop nhieu, he nhieu, hoc thieu
ho chieu » theo chieu, hoc thieu, doi chieu
cua nang » chua nang, cua dang, cua hang
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
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 nhieu) OR (ho chieu)) tang - ((hanh trinh) OR (hanh chinh)) cua nang cong dan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho nhieu) or (ho chieu)) tang - ((hanh trinh) OR (hanh chinh)) cua nang cong dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho nhieu) or (ho chieu)) tang - ((hanh trinh) OR (hanh chinh)) cua nang cong dan toan ban*.
