Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
thanh vi » hanh vi, thanh va, thanh ve
te sach » toc sach
van cam » van nam, van dam, ban cam
van cau » van dau, van hau, van chat
van lam » van nam
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
luc va » duc va, tuc va, loc va
vi cua » vai cua, di cua
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: te sach y nang x hoi. hieu ((((van cam) OR (van cau))) or (van lam)) luc va thanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang x hoi. hieu ((((van cam) OR (van cau))) OR (van lam)) luc va thanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang x hoi. hieu ((((van cam) OR (van cau))) or (van lam)) luc va thanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y nang x hoi. hieu ((((van cam) OR (van cau))) or (van lam)) luc va thanh vi cua tre*.
