Perhaps you should try some spelling variations:
tu sach » thu sach, te sach, tu cach
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
cac xuc » cac nuoc, chat xuc, cac cuoc
dao thi » do thi, dan thi, dang thi
thi cuu » thi cuc, thi huu, thi cu
cuu tre » cua tre, cau tren, cau treo
va dao » ca dao

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) ky nang xa hoi. lieu va ((cac xuc) or (cam xuc)) va dao thi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ky nang xa hoi. lieu va ((cac xuc) OR (cam xuc)) va dao thi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ky nang xa hoi. lieu va ((cac xuc) or (cam xuc)) va dao thi cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ky nang xa hoi. lieu va ((cac xuc) or (cam xuc)) va dao thi cuu tre*.
