Perhaps you should try some spelling variations:
hanh trinh » canh tranh
bien tinh » bi tinh, yen tinh, diep tinh
cong danh » cuong danh, cong dan, cong thanh
cua tong » cua cong, cua dong, cua nong
cong anh » dong anh, hong anh, cong thanh
tuan ban » tuan bang, toan ban, luan ban
ho bien » pho bien, hoa bien, so bien

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 bien tinh - ((hanh trinh) OR (hanh chinh)) cua tong ((cong anh) OR (cong danh)) tuan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho bien tinh - ((hanh trinh) or (hanh chinh)) cua tong ((cong anh) OR (cong danh)) tuan ban~".
• Adding a wildcard symbol may retrieve word variants: ho bien tinh - ((hanh trinh) or (hanh chinh)) cua tong ((cong anh) OR (cong danh)) tuan ban*.
