Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
chat xuc » cam xuc, chao xu, chat cua
chat huu » pham huu
su sach » so sach, vu sach
dan vai » dan va, dan tai, dan vat
nang xa » nang x, lang xa, nang ma
cuu tre » cua tre, cau tren, cau treo
sach ky » sac ky, sach y, sach ty
ca dan » cac dan, ca dao
cua tu » cua tuc, cua su, cua cu

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 van ((chat xuc) OR (chat huu)) ca dan vai ((cuu tre) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. hieu van ((chat xuc) OR (chat huu)) ca dan vai ((cuu tre) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. hieu van ((chat xuc) OR (chat huu)) ca dan vai ((cuu tre) or (cua tu))*".
