Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
cham xuc » cam xuc, chat xuc, cham soc
lang xa » lang ha, dang xay, lang van
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
cua tre » cua te, cuu tre, cua triet
su sac » su sach, su cac, su xac
o lang » hoa lang, hoi lang

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