Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, tu cach
te sach » toc sach
cac xuc » cam xuc, cac nuoc, chat xuc
dao thi » do thi, dan thi, dang thi
thi huu » thi hue, thi thuy
huu tre » huu tri, cuu tre, huu them
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van nang
xuc va » duc va, tuc va, luc va
va dao » ca dao

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

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