Perhaps you should try some spelling variations:
luan nhung » luan chung, luan hung, quan nhung
thanh dung » thanh duong, thanh tung, thanh hung
hanh dung » anh dung, hanh dong, manh dung
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan ban » van ban
ha tinh » va tinh, may tinh
ho ha » pho ha, ho hap, o 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: ho ha tinh - ((hanh dung) OR (thanh dung)) luan nhung ((cong dan) OR (cong tan)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ha tinh - ((hanh dung) OR (thanh dung)) luan nhung ((cong dan) or (cong tan)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ha tinh - ((hanh dung) OR (thanh dung)) luan nhung ((cong dan) or (cong tan)) toan ban*.
