Perhaps you should try some spelling variations:
dang thanh » dong thanh, dang hanh, hoang thanh
hanh trinh » canh tranh, hanh chinh
mot chieu » doi chieu, ho chieu
chua xang » chua nang, chuc nang, chu bang
cong dang » cong dong, cong dan, cong dung
thanh cac » hanh cac, thanh bac, thanh ca
cua xang » cua dang, cua hang, cua lang
doi chi » doi khi

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: ((mot chieu) OR (doi chi)) sach - hanh trinh ((cua xang) OR (chua xang)) cong dang thanh cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (doi chi)) sach - hanh trinh ((cua xang) OR (chua xang)) cong dang thanh cac~".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (doi chi)) sach - hanh trinh ((cua xang) OR (chua xang)) cong dang thanh cac*.
