Perhaps you should try some spelling variations:
hanh trang » thanh trung, canh tranh, hanh trinh
hoc thieu » toc thieu
hanh tram » hanh tam, thanh tran, thanh tra
dung cong » dung trong
van dung » van dong, xay dung, tin dung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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: ((hoc thieu) OR (hoc hien)) tach - ((hanh tram) OR (hanh trang)) van dung cong dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (hoc hien)) tach - ((hanh tram) OR (hanh trang)) van dung cong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (hoc hien)) tach - ((hanh tram) OR (hanh trang)) van dung cong dan than cap*.
