Perhaps you should try some spelling variations:
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
xa dung » xay dung, va dung, a dung
xa dong » ha dong, van dong, lao dong
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, ly nang, v nang
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 sach y nang xa hoi. hieu ve cam xuc ((xa dung) OR (xa dong)) tai ((cua vat) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. hieu ve cam xuc ((xa dung) OR (xa dong)) tai ((cua vat) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu ve cam xuc ((xa dung) OR (xa dong)) tai ((cua vat) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. hieu ve cam xuc ((xa dung) OR (xa dong)) tai ((cua vat) or (cuu tre))*.
