Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
van nhung » van nhuong, van hung, van phung
cong dan » cong san, cong tan, huong dan
dan khan » dan khanh, dan chan, dan than
khan cap » khan ap, than cap, khoan cam
po ha » pho ha, so ha, ho ha
o ha » y ha, _ ha

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: ((o ha) OR (po ha)) tinh - hanh trinh ((van nhung) OR (va nhung)) cong dan khan cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((o ha) or (po ha)) tinh - hanh trinh ((van nhung) OR (va nhung)) cong dan khan cap~".
• Adding a wildcard symbol may retrieve word variants: ((o ha) or (po ha)) tinh - hanh trinh ((van nhung) OR (va nhung)) cong dan khan cap*.
