Perhaps you should try some spelling variations:
dinh thi » dinh tri
van dinh » van minh, van dich, va dinh
cuu tre » cau tren, cau treo
duc van » duc va, duc tan, duc manh
cua tre » cua te, cua triet, dua tren
nang xa » nang x, lang xa, nang ma
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
ve cam » ve cham, va cam, ve cai
su sac » su sach, su cac, su xac

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 nang xa hoi. hieu ((ve cam) or (ve cac)) duc van dinh thi ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ((ve cam) OR (ve cac)) duc van dinh thi ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ((ve cam) or (ve cac)) duc van dinh thi ((cua tre) OR (cuu tre))*".
