Perhaps you should try some spelling variations:
gianh lai » gian lan
toc sach » hoc sach, doc sach, thuoc sach
va gianh » va gian, van giang, va giai
lai cua » dai cua, hai cua, lai chau
cam duc » cam xuc, cao duc, nam duoc
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
cua tre » cua te, cuu tre, cua triet

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) OR (toc sach)) ky lang xa hoi. hieu va ((cam duc) OR (pham duc)) va gianh lai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) ky lang xa hoi. hieu va ((cam duc) or (pham duc)) va gianh lai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) ky lang xa hoi. hieu va ((cam duc) or (pham duc)) va gianh lai cua tre*.
