Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
nang xa » nang x, nang ma, mang xa
va hanh » van hanh, va thanh, va danh
lang xa » lang ha, dang xay, lang van
sach ky » sac ky, sach y, sach ty
vi cua » vai cua, di cua
xuc va » duc va, tuc va, luc va
ve cai » va cai, ve cac, ve tai
va cao » va cac, va co, va dao
cua te » cua tu

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