Perhaps you should try some spelling variations:
thuoc sach » nuoc sach, thuat sach, thuoc sinh
hoc sach » hoc sinh, hoc cac, hoc anh
nang mai » nang ma, nang tai, lang mai
va tinh » may tinh
va dinh » van dinh, va kinh, vu dinh
cuu tre » cua tre, cau tren, cau treo
mai hoi » mai khoi, dai hoi, lai hoi
y nang » ky nang, ly nang, v nang
vi cuu » vi luu, vinh cuu
va cam » va cham, va cac, va cao

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: ((thuoc sach) OR (hoc sach)) y nang mai hoi. lieu va cam xuc ((va dinh) OR (va tinh)) vi cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuoc sach) or (hoc sach)) y nang mai hoi. lieu va cam xuc ((va dinh) OR (va tinh)) vi cuu tre~".
• Adding a wildcard symbol may retrieve word variants: ((thuoc sach) or (hoc sach)) y nang mai hoi. lieu va cam xuc ((va dinh) OR (va tinh)) vi cuu tre*.
