Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
cham xuc » cam xuc, chat xuc, cham soc
hanh dai » hanh dao, vanh dai, thanh dat
hanh tai » thanh tai, hang tai, han tai
lang xa » lang ha, dang xay, lang van
cua tre » cua te, cuu tre, cua triet
su sac » su sach, su cac, su xac
o lang » hoa lang, hoi lang
xuc va » duc va, tuc va, luc va

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 dai) OR (hanh tai)) 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 dai) OR (hanh tai)) 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 dai) OR (hanh tai)) cua tre*.
