Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
su sach » so sach, vu sach
lai cua » dai cua, hai cua, lai chau
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
ty nang » ky nang, ty hang, ly nang
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 ((ty nang) OR (ty xang)) co loi. hieu ve cham ((xuc va) or (tuc va)) thanh lai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty nang) OR (ty xang)) co loi. hieu ve cham ((xuc va) OR (tuc va)) thanh lai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty nang) OR (ty xang)) co loi. hieu ve cham ((xuc va) or (tuc va)) thanh lai cua tre*".
