Perhaps you should try some spelling variations:
sach vay » sach va, sach nay, sach dao
sach hay » sach han, sach ha, sach nay
nhan duc » nhan duoc, nhan luc, phan duc
nang xa » nang x, lang xa, nang ma
va nhan » van nhan, ca nhan, va phan
va hanh » van hanh, va thanh, va danh
vi cua » vai cua, di cua
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: te ((((sach vay) OR (sach hay))) OR (sach y)) nang xa hoi. lieu va nhan duc va hanh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach vay) OR (sach hay))) or (sach y)) nang xa hoi. lieu va nhan duc va hanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: te ((((sach vay) OR (sach hay))) or (sach y)) nang xa hoi. lieu va nhan duc va hanh vi cua te*.
