Perhaps you should try some spelling variations:
chat xuc » chat huu, cam xuc, chao xu
sach van » sach han, sach va, bach van
tu sach » thu sach, su sach, te sach
cua tre » cua te, cua triet, dua tren
xa hanh » xa thanh, xa khanh, va hanh
va chat » van chat, va phat, cao chat
nang xa » lang xa, nang ma, mang xa
hieu va » lieu va, hieu qua
cuu tre » cau tren, cau treo
xuc xa » tuc xa, buc xa

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