Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
su sach » so sach, vu sach
sach ty » sach y, sach tu, sach thu
lai cua » dai cua, hai cua, lai chau
cua tre » cua te, cuu tre, cua triet
nang co » nang cao, nang doc, nang noi
ty nang » ky nang, ty xang, ty hang
ve cam » ve cham, va cam, ve cai
ve cac » va cac, vien cac
xuc va » tuc va, luc va, xac va
co loi » co hoi

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 ty nang co loi. hieu ((ve cam) or (ve cac)) ((xuc va) OR (duc va)) thanh lai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang co loi. hieu ((ve cam) OR (ve cac)) ((xuc va) OR (duc va)) thanh lai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang co loi. hieu ((ve cam) or (ve cac)) ((xuc va) OR (duc va)) thanh lai cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ty nang co loi. hieu ((ve cam) or (ve cac)) ((xuc va) OR (duc va)) thanh lai cua tre*.
