Perhaps you should try some spelling variations:
thanh te » thanh ve, thanh de, thanh le
su sach » so sach, vu sach
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
va cham » va chat, va tham
cua tre » cua te, cuu tre, cua triet
xuc va » tuc va, luc va, xac va
te cua » tue cua, le cua, de cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach _ lang xa hoi. hieu va cham ((((xuc va) OR (duc va))) or (tuc xa)) thanh te cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach _ lang xa hoi. hieu va cham ((((xuc va) OR (duc va))) OR (tuc xa)) thanh te cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach _ lang xa hoi. hieu va cham ((((xuc va) OR (duc va))) or (tuc xa)) thanh te cua tre*".
