Perhaps you should try some spelling variations:
ban hanh » ban hang
te sach » toc sach
sach ky » sac ky, sach y, sach ty
cau xuc » cam xuc, cau truc, chat xuc
cau luc » cau truc, cau phuc
cua tre » cua te, cuu tre, cua triet
vi cua » vai cua, di cua
x hoi » o hoi, x ho, 5 hoi

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang ((x hoi) OR (xa hoi)). lieu va ((cau xuc) or (cau luc)) ban hanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ((x hoi) OR (xa hoi)). lieu va ((cau xuc) OR (cau luc)) ban hanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ((x hoi) OR (xa hoi)). lieu va ((cau xuc) or (cau luc)) ban hanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang ((x hoi) OR (xa hoi)). lieu va ((cau xuc) or (cau luc)) ban hanh vi cua tre*.
