Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
sach tham » sach nha
sach thu » sach thue, sach thieu, cach thuc
lai cua » dai cua, hai cua, lai chau
ve chat » va chat, van chat
nang co » nang cao, nang doc, nang noi
hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
co loi » co hoi
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa

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 thu) OR (sach tham)) nang co loi. hieu ve chat ((xuc va) or (tuc va)) thanh lai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach thu) OR (sach tham)) nang co loi. hieu ve chat ((xuc va) OR (tuc va)) thanh lai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach thu) OR (sach tham)) nang co loi. hieu ve chat ((xuc va) or (tuc va)) thanh lai cua tre*".
