Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
hanh vai » hanh vi, hanh va, hanh tai
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
cau luc » cau truc, cau phuc
cau loc » hau loc, cau hoc, cau long
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
ly hang » ly quang
ly nang » ky nang, ly vang, ly quang
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ((ly nang) OR (ly hang)) x hoi. hieu ve ((cau loc) or (cau luc)) va hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ((ly nang) OR (ly hang)) x hoi. hieu ve ((cau loc) OR (cau luc)) va hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ((ly nang) OR (ly hang)) x hoi. hieu ve ((cau loc) or (cau luc)) va hanh vai cua tre*".
