Perhaps you should try some spelling variations:
chat xuc » chat huu, cam xuc, chao xu
dinh van » sinh vat
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
dinh va » dinh ve, tinh va, sinh va
va chat » van chat, va phat, cao chat
hieu va » lieu va, hieu qua
nang ma » tang ma, sang ma, nang cao
nang xa » nang x, lang xa, mang xa
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va

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 ky ((nang xa) OR (nang ma)) hoi. hieu va chat xuc va ((dinh va) OR (dinh van)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((nang xa) or (nang ma)) hoi. hieu va chat xuc va ((dinh va) OR (dinh van)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((nang xa) or (nang ma)) hoi. hieu va chat xuc va ((dinh va) OR (dinh van)) cua tre*.
