Perhaps you should try some spelling variations:
dung cong » dung trong
van dung » van dong, xay dung, tin dung
sach ky » sac ky, sach y, sach ty
cua tre » cua te, cua triet, dua tren
xuc van » duc van, luc van, vuc van
su sach » so sach, vu sach
ve cham » va cham, ve chat, vu cham
nang xa » nang x, lang xa, nang ma
cuu tre » cau tren, cau treo
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 sach ky nang xa hoi. hieu ((ve cam) OR (ve cham)) xuc van dung cong ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. hieu ((ve cam) OR (ve cham)) xuc van dung cong ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. hieu ((ve cam) OR (ve cham)) xuc van dung cong ((cua tre) or (cuu tre))*".
