Perhaps you should try some spelling variations:

van dinh » van minh, van dich, va dinh
dinh tri » chinh tri
nang xa » nang x, lang xa, nang ma
duc van » duc va, duc tan, duc manh
cua tre » cua te, cuu tre, cua triet
pu xac » su xac
xac ky » cac ky, sac ky, bac 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: pu xac ky nang xa hoi. hieu ((ve cam) or (((vien cac) OR (vien bach)))) duc van dinh tri cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: pu xac ky nang xa hoi. hieu ((ve cam) OR (((vien cac) OR (vien bach)))) duc van dinh tri cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "pu xac ky nang xa hoi. hieu ((ve cam) or (((vien cac) OR (vien bach)))) duc van dinh tri cua tre*".
