Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
cham xuc » cam xuc, chat xuc, cham soc
va danh » va dinh, va hanh, dia danh
te sach » toc sach
hieu ve » hieu va
lang xa » lang ha, dang xay, lang van
cua tre » cua te, cuu tre, cua triet
sach o » sach lo, sac o, sach y
o lang » hoa lang, hoi lang
va dan » ca dan, va dao, va dau
vi cua » vai cua, di cua

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 o lang xa hoi. ((hieu ve) OR (hieu van)) cham xuc ((va danh) OR (va dan)) vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach o lang xa hoi. ((hieu ve) or (hieu van)) cham xuc ((va danh) OR (va dan)) vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach o lang xa hoi. ((hieu ve) or (hieu van)) cham xuc ((va danh) OR (va dan)) vi cua tre*.
