Perhaps you should try some spelling variations:
nam truc » nam truoc, nam thuc, nam trung
te sach » toc sach
xa hanh » xa thanh, xa khanh, va hanh
truc xa » tuc xa, truc va, truoc xay
hieu va » lieu va, hieu qua
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, ly nang, may nang
ma hoi » mai hoi, xa hoi, me hoi
va nam » van nam, ha nam, va nay
v nang » va nang, vu nang, van nang
vi cuu » vi luu, vinh cuu

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: te sach ((y nang) OR (v nang)) ((ma hoi) OR (ma hoa)). hieu va nam truc xa hanh vi cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (v nang)) ((ma hoi) or (ma hoa)). hieu va nam truc xa hanh vi cuu tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) OR (v nang)) ((ma hoi) or (ma hoa)). hieu va nam truc xa hanh vi cuu tre*.
