Perhaps you should try some spelling variations:
dinh thi » dinh tri
nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, vu cham
duc van » duc tan, duc manh, duc phan
thi cua » thai cua, thi cuc, tri cua
cua tre » cua te, cuu tre, cua triet
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ve cam » ve cac, va cam, ve cai

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 cham)) ((duc van) or (duc va)) dinh thi cua 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 cham)) ((duc van) OR (duc va)) dinh thi cua 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 cham)) ((duc van) or (duc va)) dinh thi cua tre*".
