Perhaps you should try some spelling variations:
thien van » thi van
thanh vai » thanh hai, thanh van, thanh tai
toc sach » hoc sach, doc sach, thuoc sach
nang xa » nang x, lang xa, nang ma
qua ban » qua quan
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet

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) or (toc sach)) ky nang xa hoi. thien van nam ((qua ban) OR (cua ban)) thanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) ky nang xa hoi. thien van nam ((qua ban) OR (cua ban)) thanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (toc sach)) ky nang xa hoi. thien van nam ((qua ban) OR (cua ban)) thanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (toc sach)) ky nang xa hoi. thien van nam ((qua ban) OR (cua ban)) thanh vai cua tre*.
