Perhaps you should try some spelling variations:
ban hanh » ban hang
cham xuc » cam xuc, chat xuc, pham duc
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
hieu va » lieu va, hieu qua
da cuu » da cu, da cua, da suu
da cau » dat cau, va cau
x hoi » xa hoi, o hoi, x ho

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

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