Perhaps you should try some spelling variations:
ban hanh » ban hang
tu sach » thu sach, su sach, te sach
cua tre » cua te, cua triet, dua tren
va hanh » van hanh, va thanh, va danh
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
cuu tre » cau tren, cau treo
y nang » ky nang, ly nang, v nang
ve cac » va cac, vien cac

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 y nang xa hoi. hieu ve cac xuc ((va hanh) or (ban hanh)) vai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu ve cac xuc ((va hanh) OR (ban hanh)) vai ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu ve cac xuc ((va hanh) or (ban hanh)) vai ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu ve cac xuc ((va hanh) or (ban hanh)) vai ((cua tre) OR (cuu tre))*.
