Perhaps you should try some spelling variations:
truong doi » truong dai, trong doi, truong hoi
xa truong » cac truong
nam thuc » nam thuoc, am thuc, nam thu
so sach » so sanh, bo sach, co sach
sach ty » sach y, sach tu, sach thu
doi cua » dai cua, hoi cua
cam tuc » cam xuc, cam tu, dam thuc
hieu va » lieu va
ty nang » ky nang, ty xang, ty hang
cua tre » cua te, cuu tre, cua triet
x hoi » xa hoi, o hoi, x ho

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: so sach ty nang x hoi. ((hieu va) OR (hieu qua)) ((cam tuc) OR (nam thuc)) xa truong doi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty nang x hoi. ((hieu va) or (hieu qua)) ((cam tuc) OR (nam thuc)) xa truong doi cua tre~".
• Adding a wildcard symbol may retrieve word variants: so sach ty nang x hoi. ((hieu va) or (hieu qua)) ((cam tuc) OR (nam thuc)) xa truong doi cua tre*.
