Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
va hanh » van hanh, va thanh, va danh
xang xa » mang xa, ang xa, dang xay
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
sach ty » sach y, sach tu, sach thu
va tinh » may tinh
vi cua » vai cua, di cua
ve cac » va cac, vien cac
cac tu » cac thu, cach tu, cac du
cua te » cua tu

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((xang xa) OR (lang xa)) hoi. hieu ve cac tu ((va hanh) OR (va tinh)) vi cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((xang xa) or (lang xa)) hoi. hieu ve cac tu ((va hanh) or (va tinh)) vi cua te*.
