Perhaps you should try some spelling variations:
sach tham » sach nha
tham nang » nham nang, tham lang, tham nhung
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
thanh di » thanh doi, thanh de, thanh do
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
ve pham » v pham, ve phan, ve phat
duy va » duy vat, duy van, day va
di cua » dai cua, doi cua, de cua

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 tham nang xa hoi. hieu ((ve pham) OR (vi pham)) duy va thanh di cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu sach tham nang xa hoi. hieu ((ve pham) or (vi pham)) duy va thanh di cua triet*.
