Perhaps you should try some spelling variations:
thanh tri » thanh tra, thanh tai, chinh tri
hanh tri » hanh tai, hanh trinh, hanh triet
dang van » hoang van, hang va
xuc toan » duc toan, xuan toan, quoc toan
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
van hoi » van hoa, van hoc, van hoe
sac ky » cac ky
ve cam » ve cham, ve cac, va cam

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su ((sac ky) or (sai ky)) dang van hoi. hieu ve cam xuc toan ((hanh tri) OR (thanh tri)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (sai ky)) dang van hoi. hieu ve cam xuc toan ((hanh tri) OR (thanh tri)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) or (sai ky)) dang van hoi. hieu ve cam xuc toan ((hanh tri) OR (thanh tri)) cua tre".
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) or (sai ky)) dang van hoi. hieu ve cam xuc toan ((hanh tri) OR (thanh tri)) cua tre*.
